Bath thermometer: types, features. How to choose a thermometer for a bath?

The uniqueness of the bathhouse lies in the fact that it must maintain certain climatic conditions. If the temperature is incorrect or the humidity level is inappropriate, the benefits of the Russian bath will be significantly reduced or completely lost. To maintain an optimal microclimate, some accessories will be useful, in particular, a bath thermometer.

This device is simple and quite cheap, but it will become a faithful assistant in the steam room: the thermometer will warn you about an increase/decrease in the desired temperature, using it you can control the combustion process.

It is known that it is important to properly flood the bathhouse. If the temperature is higher than normal, then there is a chance of getting heatstroke, and a long stay in such a steam room, instead of being cheerful and full of energy, will give you fatigue and loss of strength. Too low a temperature will not provide the benefits of bath procedures, which is also bad.

Measuring the temperature in the steam room

Nowadays it is difficult to imagine a steam room without a thermometer, although 20-30 years ago it was not considered such a necessary thing. What can I say, in some village baths you won’t see it even now. There, the temperature is determined the old fashioned way - by how it feels. This was done many decades ago, in bathhouses in black and then in white.

And since they managed quite well without it, then maybe it’s not really needed now? Maybe the presence of this little thing is just a tribute to the modern bath interior? Let's try to answer these questions.

Do you need a thermometer in a bath?

A true broom fan and couple knows everything about their favorite bathhouse and, in particular, about the capabilities of the installed stove. Of course, he knows when to start heating, how much wood will be needed and how quickly it will cook. The time of year, weather conditions, type of firewood and structural features leave some imprint on the preparation of a bathhouse, but still an experienced bath attendant quite accurately determines how much it needs to be heated and what temperature it will ultimately be.

Then maybe it is needed for control during bath procedures? But even here we can answer that no. Patting yourself with brooms or warming yourself on a shelf, you certainly will not be guided by a thermometer about the time when to stop, but solely by a feeling of comfort. Everything is simple here: it’s hot - you go lower, it’s cool - you give in to the parka. Many people have probably noticed how the same t is perceived differently. It happens that you are ready to sit in a hot steam room for at least half an hour, but sometimes you can’t even sit for 10 minutes. And here it is not so important what the thermometer shows - the main thing is the sensations.

It turns out that this device will really come in handy for those who find themselves in an unfamiliar bathhouse, have built a new one, or are simply inexperienced.

But even in this case, rely on the thermometer, and don’t make a mistake yourself. After all, there is one interesting point here - everyone’s baths are different, and accordingly there will be different air conditions.

And it depends mainly on the type of stove - iron or brick, open heater or closed. So it turns out that + 60 degrees C in a simple rural bathhouse is not at all the same as in a bathhouse complex, where at this temperature you can freeze, with, of course, low humidity.

So why is a thermometer still needed? The answer is very simple - convenience. Still, it’s more convenient with it:

And it is simply necessary to prevent water from freezing in systems (shower cabin, heat exchangers, built-in tanks, etc.).

Types of thermometers

Thermometers for measuring t appeared a long time ago, but special ones for baths and saunas only recently, which, however, did not stop them from immediately flooding store shelves.

Considering that a thermometer for a steam room is more of an interior item, its main advantage is its appearance. It should organically fit into and complement the decor of the steam room and give the mood. That is why modern temperature meters are cheerful bathhouse attendants, tubs, mugs, brooms, samovars, wishes for health and light steam.

Despite all the frivolity of these products and a slightly larger error in measurements than other similar devices, they are fully consistent with their purpose.

All bath thermometers are household thermometers and are divided according to their design into three categories: liquid, dial and digital.

Liquid (TTZh-M)

Or capillary - the most common, contain at their base a straight tube filled with an organic liquid. Previously, mercury was used entirely as a filler, but now this is a rarity; it is replaced by toluene, alcohol or kerosene. The price of scale divisions varies greatly among many, but the range of temperature measurements is usually from O to + 140 - 160 degrees Celsius

Taking into account the specific application of these products, they must meet a number of requirements, which is what most bona fide manufacturers do:

- do not contain hazardous substances, - withstand high t values, - be resistant to changes in humidity, - be durable and safe.

The basis for the manufacture of household t meters are many affordable and harmless materials, mainly based on plastics, but, of course, only wood would be appropriate in a bathhouse.

Switches

They are also called mechanical or bimetallic. In appearance, they are a little reminiscent of an ordinary watch: a round scale, numbers, but there is only one hand, which indicates the temperature value at the moment.

The principle of their operation is based on the ability of the sensing element (made in the form of a spring) to change the degree of compression depending on the ambient t.

Considering that the measurement error is higher than that of capillary instruments, the cost of divisions is higher - 5-10g.C

The advantages of such thermometers, in addition to their appearance, include a large scale. You can see how many degrees there are without getting off the shelf.

Digital

Very accurate and convenient devices. Small plastic or metal boxes with a clear LCD display. The temperature sensor is remote, built into the tip of the wire, i.e. This electronic device is intended to be placed outside the steam room.

Among the advantages, we note: temperature control at a distance, high accuracy and good perception of information.

There are also disadvantages: periodic replacement of batteries, increased error when measuring extreme temperature limits.

These are the types of devices that sauna lovers now equip their steam rooms with. As we see, all models have advantages and disadvantages, so the choice is yours.

How to install a thermometer in a moonshine distillation system

There are several options for using a device for measuring temperature - purchasing equipment with an already installed sensor or installing it yourself. In the first case, the manufacturer has already taken into account the specifics of mounting the device, and the product itself has been selected in accordance with the operating conditions.

Such models are initially easy to use, and if preference is given to units manufactured by professional companies, then you just need to study the alcohol production technology and the attached instructions. There are units where the measuring element is mounted in the evaporator or in the container itself for distilling the mash. If we compare these types of equipment regarding the accuracy of measurement in the process of preparing alcohol, then the installation option in the evaporator part is preferable.

The purchased thermometer should be securely secured inside the tank of the moonshine still!

• Decide on the location where the sensor will be located. Most often they are mounted in the upper part of the distillation cube.
• Estimate the size of the installation cylinder, which should come complete with a thermometer for the moonshine still, and make a hole of the required diameter in the body of the distillation cube.
• Select the bolt and nut that you will use to secure the installation cylinder inside the still body.
• Prepare a silicone gasket that will maintain the tightness of the cylinder installation location. It is better not to buy rubber products, since this material will give the finished moonshine an unpleasant odor and taste. In addition, with regular heating, such a gasket will quickly lose its properties.
• Insert the cylinder into the prepared hole along with the seal, secure it with a bolt and nut.
• Mount the thermometer inside the installation cylinder.

If you already have a system for making homemade alcohol, but it lacks a thermometer, then you can install it yourself. Technically, this is not difficult; it is necessary to prepare the hole and seals so that the tightness is not compromised. If a pressure cooker is used as a moonshine still, then a thread is made in the lid, gaskets that are resistant to temperature changes and the device itself are inserted.

It is important that the element does not come into contact with the surface of the apparatus, otherwise the indicators will be distorted and data will be recorded from the walls of the cube, not the environment

Adjusting indicators

As a rule, thermometers go on sale already calibrated. But failures during operation and inaccuracy of indicators are also possible. In this case, the device can be adjusted. For example, in bimetallic, adjustment is usually possible with a bolt or a screwdriver.

Sometimes it is necessary to calibrate an electronic device or two for installation in a cube and column so that they show the exact temperature. You need a container with cold water in which ice floats (conditionally, its temperature is 0°C). Immerse the probe in this water for at least 5 cm for 3 minutes.

Then press “CAL” (there is such a button for calibration) and hold for 3 seconds. The thermometer will adjust to zero temperature. After this, shake the probe in water with ice. If the readings change, perform the calibration again.

Regarding digital and infrared thermometers, see the instructions. As a rule, they do not need additional adjustment, and the error is no more than 0.2 degrees. Self-calibration may lead to even greater inaccuracy.

Optimal performance in a steam bath

There are certain standards for humidity and temperature readings in different rooms of the bathhouse. By adhering to these standards, you will make your stay comfortable and safe. First, you need to take into account that the higher the air temperature, the lower the humidity should be. Excessive levels of both parameters are dangerous to health.

Each room has its own requirements:

Selection criteria

To figure out which thermometer is best to choose for a bath, you need to pay attention to a number of criteria

Accuracy. Here, as can be understood from the above, all devices have a certain error in the readings. Electronic thermometers will be the best according to this criterion, although they also have a minimal error.

Personal preferences and cost of the device

When selecting a bath thermometer, you should pay attention to the appearance of the device so that it matches the interior of the room. But if you want something exclusive, you’ll definitely have to fork out the cash.

Measuring scale

When selecting a device, this point should also be taken into account, because there is no point in paying for extra degrees. For example, most models have a temperature scale of up to 180 degrees. As a rule, you don’t need that much for a bath. Devices with a maximum level of 120 degrees will be sufficient.

The versatility of the device. Not long ago, thermohygrometers appeared on the market, which combine the functions of both a hygrometer and a thermometer. After purchasing one device, it becomes possible to control not only the room temperature, but also the humidity.

In general, today there are quite a large number of devices on the market from different manufacturers, varying in materials of manufacture, number of functions and principles of operation. This allows each bathhouse owner to choose the best solution, which will make the process of using the bathhouse as enjoyable and useful as possible.

For a review of the bath thermometer, see below.

Requirements for bath thermometers

A bath thermometer helps create the necessary microclimate in the room, which will be favorable for all visitors. Measuring instruments will warn you if the permissible temperature limit is exceeded. In addition, they can be used to control the combustion process. By looking at the temperature mark, you will know exactly whether you still need to add more firewood. At +60 degrees, you can start steaming brooms.

Measuring instruments for a bath are constantly influenced by changes in temperature and humidity, and therefore must meet certain requirements:

Manufacturers

Bath hats: features and types.
how to make a bath hat with your own hands: patterns, photos, instructions If we talk about manufacturers of bath thermometers, the most famous are Finnish companies. Probably the most famous among them is Sawo. This company from the country of Suomi aims to produce high-quality thermometers that are affordable. These devices are made from the very beginning for use in baths and saunas, thanks to which they have high quality, individual and pleasant design. Typically, thermometers from this company are made of wood.

Another well-known manufacturer of such products from Finland is Harvia. Its products are slightly more expensive, but it mainly specializes in creating thermohygrometers. A distinctive feature of its products is that they are made from deresined Finnish pine.

Thermometers from the Finnish company Rento, which usually produces them from aluminum, are quite good. They are distinguished by simplicity and accessibility.

But some of the most expensive and brightest thermometers are devices from another Finnish company, Cariitti. They are characterized by the presence of frosted glass, a scale made of stainless steel, and backlighting. Installation of such thermometers is carried out exclusively when covering the bathhouse with panels.

The Austrian company Sentiotec has quite interesting products of this type. It produces thermometers, hygrometers and thermo-hygrometers with wood housings and uses advanced technology to display the most accurate data possible.

The German company EOS Werke Gunter GmbH can boast of some pretty good devices. It is considered one of the most technologically advanced manufacturers of this type of equipment on the market. Usually makes hygrometers and thermometers for baths at a fairly affordable price. Another advantage is that the body of almost all devices is made of maple and walnut wood.

And if we talk about domestic manufacturers, then the products of such and “Teplodar” are presented on the market. The products are especially interesting - they make their products in a body made of natural stone.

Types of measuring devices for baths

Based on the principle of operation, there are several types of thermometers: digital (electronic) - from 230 rubles, most accurate; capillary (liquid) - from 300 rubles, have a small error in readings, pointer (mechanical) - from 450 rubles. Least accurate. It should be noted that the price of measuring devices affects the quality. Inexpensive mechanical thermometers have a maximum rated error. Often, cheap devices are made from low-quality materials that cannot withstand constant changes in temperature and humidity.

Dial thermometers for baths

These bimetallic devices look like regular watches. Only the hand on the dial shows the temperature in the range from 0 to 120 degrees, and not the time.

The spring in such equipment changes the degree of compression with temperature changes. Accordingly, the error of mechanical devices is higher compared to liquid ones. The advantages include a rather large dial and various design options.

Capillary bath thermometers

Otherwise they are called liquid. Typically, liquid products provide readings in the range from 0 to 160 degrees. These devices consist of a straight tube containing an organic liquid (kerosene, toluene, alcohol). Previously, the filler of such devices was mercury.

However, mercury equipment is strictly prohibited from being installed in a steam room. If the glass flask is damaged, then in conditions of high humidity and temperature the evaporation of mercury will cause irreparable harm to your health.

Electronic bath thermometers

This device is distinguished by practicality and maximum accuracy. It is a compact case made of stainless steel or heat-resistant plastic with a liquid crystal display. The device can withstand temperatures up to +235 degrees, while its maximum error can be 0.5 degrees.

It is often equipped with a remote wired or wireless sensor and installed outside the steam room. Some models also have a built-in sound warning system when the required temperature is reached.

It is most convenient to install a remote thermometer for a bath in the dressing room or rest room. In this case, only the sensor is mounted in the steam room itself. This allows you to control the temperature from a distance. The device is especially popular in commercial baths with several steam rooms, since some models involve connecting three or more sensors to a common system.

Disadvantages include high cost and the need to periodically replace batteries. It is also not always convenient, since you need to leave the steam room to check the temperature. However, of all the varieties, a thermometer with a bath sensor is considered the most durable and high-quality.

Hygrometers for baths

Staying in a room with high humidity and air temperature can be hazardous to health. Therefore, hygrometers are installed in the bathhouse to measure humidity levels (from 300 rubles apiece) and control the microclimate in the steam room. When purchasing a device, give preference to models with a wooden case. They are the safest to use.

Sauna stations for steam room

Bath stations are considered a definite innovation in steam rooms and are especially relevant in Russian baths. The most common models of bath stations combine both a thermometer and a hygrometer.

In some cases, the device can even be equipped with a barometer, which determines the pressure in the steam room. Such a device is useful for hypo- and hypertensive patients, who are recommended to steam only at certain pressure levels.

The disadvantages of the device include expensive repairs. If one of the devices breaks down, you must take the entire set to the workshop. However, a high-quality bath station with the most accurate devices will last for many years without breakdowns, although it will cost more.

Types of devices

Let's consider several popular models. They can be mercury (capillary), pointer, electronic and complex, which combine several instruments (hygrometer, barometer, clock):

Electronic (digital)

The device has a remote temperature sensor, an LCD monitor, and meets all European standards. The product is considered the most modern, advanced, and will fit perfectly into the interior of the bath space. The reading error is half a degree and is characterized by increased reliability.

The electronic device, unlike other types of thermometers, must be installed outside the steam room (in the dressing room), and the sensor inside. This device is not always convenient to use; you need to go out to find out the temperature.

Mechanical (switch)

The unit is often used in saunas. This is a budget-friendly, easy-to-use, stylish device, with a bright scale that shows fairly accurate information.

The dial thermometer will perfectly complement the interior of a classic Russian bathhouse with shelves made of solid Karelian birch. The product is highly durable. The disadvantage of the device is the high error in temperature readings.

This type of device is effective at temperatures up to 120°C.

Capillary thermometer

The principle of operation is no different from a conventional thermometer. Its design feature is a glass bulb consisting of high-strength glass.

The advantage of a mercury device is its attractive appearance, combined with the classic interior of a Russian bathhouse. A serious disadvantage of the device is the increased likelihood of mercury evaporation if it breaks down, which can be harmful to health, especially at high temperatures and humidity in the sauna.

There is an analogue of the mercury device, where a tinted liquid or gallium alloy is used instead of a dangerous substance. This device measures temperature up to 180 °C.

Bath station

Another comprehensive solution for microclimate control is a sauna station. This equipment includes a thermohygrometer and barometer. All measurements are displayed on separate sections of the display, which makes the procedures even more comfortable. Despite its functionality, the equipment is quite compact and will fit into any interior.

Types of thermometers and their applicability in bath practice

A thermometer is a device for measuring the temperature of the environment, that is, air, water, soil, and so on. Naturally, in a bathhouse, temperature readings are very important. From them we can judge a number of determining factors:

In this section, we will consider bath thermometers from the point of view of their design and principles for measuring current temperature indicators.

This type is the most classic, if not standard, in the field of household temperature control devices. Its operating principle is based on the ability of certain liquid substances to change their volume depending on the ambient temperature. To ensure that the readings do not correlate with atmospheric pressure values, the vessel with the liquid reservoir and the thin tube - the capillary through which this same liquid moves - must be isolated and not have open channels communicating with the external environment. Based on the type of filler, until recently, thermometers were divided into mercury and non-mercury.

However, starting this year, the use of mercury thermometers is prohibited by the relevant convention. Based solely on safety requirements. Of the non-mercury devices in everyday life, alcohol devices are the most widely used. The working agent is alcohol: ethyl, methyl, propyl. For a better visual perception of the height of the liquid column in the capillary and reading the readings, the alcohol is colored with a pink-red pigment.

Usually watches are mechanical, however, the principle of mechanical conversion of the expansion of a bimetallic plate into the movement of a hand is embedded in such a rather extraordinary measuring device as a mechanical thermometer in a bathhouse. The main fundamental point in this case is that mechanical thermometers are contact-type devices, that is, for an accurate temperature reading, the sensitive element must be in as much contact as possible with the medium in which the measurement is being made.

It is quite obvious that the specified criteria, to a greater extent, apply to a thermometer for the furnace, especially if it is equipped with a water circuit and there is an objective need to control the temperature of the coolant. Some users fear that the mechanical filling will negatively tolerate the effects of steam.

Features and useful functions of outdoor window thermometers

When purchasing a thermometer, pay attention to its characteristics and additional features that make digital window thermometers more convenient and functional

Features and advantages of electronic outdoor thermometers

Thanks to the achievements of modern technologies, digital thermometers are able to work under different conditions and are as convenient as possible in everyday life:

• household electronic thermometers operate over a wide temperature range. For the indoor main unit, the operating range is from -10 to +50°C, the outdoor sensor maintains its performance characteristics at temperatures from -50 to +70°C. This allows the thermometers to be used in all climatic zones of Russia;
• you don’t have to worry about the safety and accuracy of the device’s readings in any weather conditions: thanks to the sealed housing, the sensor is not afraid of snow, wind, rain and scorching sun;

Thanks to the sealed housing, weather conditions cannot affect the readings of the device

• It is interesting that a radio transmitter with a thermocouple can be installed not only on the street. If you need to measure the temperature in a room or inside another object, you can place a capsule with a sensor in a greenhouse, garage, cellar, workshop and even a refrigerator;
• wireless electronic outdoor thermometers with a remote sensor can be easily placed in any convenient place; they do not have to be near a window;
• modern devices not only record temperature, but carry out full monitoring and analyze the data obtained.

Additional functions of electronic digital thermometers with a remote sensor

Modern devices have various additional features that expand the functionality of the thermometer. When choosing a thermometer, these characteristics can play an important role.

If you have a need for data analysis, make sure that the selected model is equipped with a USB port and the ability to process recorded data. If your only purpose of purchase is to find out the temperature outside, choose the simplest, most laconic thermometer model.

Additional accessories

As we said above, in addition to a hygrothermometer, you can install a barometer in the steam room, which measures the pressure in the room. This equipment is useful for people suffering from heart ailments. Please note that cheap barometers are not able to display sudden changes in pressure in a timely manner, so if you need this indicator, it is recommended to install a quality device.

Control the time you spend in the steam room - the optimal time should be no more than 15 minutes.

Dummy thermometer

The thermometer in the form of a pacifier is designed specifically for small children. But this device can only be used if the baby’s nose breathes well, and when sick it is often blocked. The sensor located on the pacifier must be in close contact with the baby's tongue to ensure reliable readings. Therefore, the child should be calm, not cry or play with the device. The thermometer measures the temperature within 2-3 minutes. The result appears on the display after a beep.

The dummy thermometer must be washed after each use. To do this, you need to disconnect the pacifier from the device with a temperature sensor and boil it for 1-2 minutes. But if the design of the device does not provide for its further disassembly, then this cannot be done. After use, it will be enough to wash it with soap and boiled water at room temperature, then dry it and put it in a case.

Bath stations

The tricky phrase “thermo-hygrometer for a bath” tells you something. Although, this is nothing more than a combined device for measuring the temperature and humidity of a steam room in real time. The Finns were the first to widely introduce combined devices. After all, it is the correct ratio of temperature and humidity that gives that legendary “golden steam” formula, so valued in the classic and real Finnish sauna.

Naturally, to complete the readings, you also need a chronometer, in other words, a bath clock. After all, as the classics say, nothing changes the passage of time like a night at the airport, a flight into space and sitting in a steam room. Some manufacturers went even further and began to equip their basic, three-position stations with an additional option - a barometer. That's right. It is important for weather-dependent people to be aware of possible weather quirks.

Important! It is quite obvious that the barometer should be located away from the steam room. There is no need to expose the precise mechanism to unnecessary stress from being close to the kingdom of fire and steam. However, any responsible manufacturer of large-format bath stations specifically speaks about this in the accompanying manuals.

Criterias of choice

When choosing a device for a bath, you need to consider:

1. Capabilities of the measuring scale. There is no point in buying a device that will show temperatures above 120 °C.
2. Your own wishes for the design of the device.
3. Temperature measurement accuracy. It is better to use electronic models. They have minimal error.

Advantages and disadvantages

Positive aspects of pointer (mechanical) instruments:

• simplicity of design;
• harmlessness;
• reliability, durability;
• low price.

The only drawback is the low measurement accuracy.

Advantages of liquid devices:

• reliability, durability;
• small measurement error;
• measurement of indicators up to 160 °C;
• low price.

If mechanical damage occurs, the glass capsule may break.

Advantages:

1. Minimum level of error.
2. Capable of measuring temperatures up to 235 °C.
3. Durability, reliability, resistance to aggressive factors.
4. Availability of additional functions.

The disadvantage is the high price.

Which thermometer for a sauna and bath to choose - options and selection rules

Good day, dear lovers of hot steam! If it is quite easy for an experienced bathhouse attendant to determine the temperature in a steam room, while for a beginner it is quite difficult to do this. Many hot steam lovers rely only on their senses.

But the results are not always adequate. Fatigue, malaise, or simply atmospheric factors may not properly affect a person’s temperature sensitivity. Therefore, in order to accurately control the temperature, you must install a bath thermometer. But what they are and what requirements they must satisfy, we’ll talk below...

Every owner of a private house probably dreams of his own bathhouse, but not a simple steam room for several people, but a modern steam room with various technical means that make bathing procedures a real pleasure. This article will discuss devices that will allow you to control the temperature, humidity and pressure in the room, which will help create a comfortable atmosphere throughout the entire session.

Where should the device be hung?

It is important to choose the right location and height for placing the thermometer. In this case, several features should be taken into account, the size of the room

Place

Principles for choosing a location:

1. It should not be hung near the door, because if it is opened frequently, it will not be able to show the exact temperature.
2. It is prohibited to place near the stove. This will compromise the accuracy of the measurement.
3. Mercury and mechanical products must be installed inside the steam room.

Electronic devices should be hung inside the dressing room or any recreation area. A temperature sensor should be placed in the steam room. It can connect to the main device via a wire or work remotely. The second option is easy to install, but may cause some errors.

Height

You also need to pay attention to the height of the device. The optimal indicator is 1.5 meters

It is important that it does not interfere with bath procedures. To accurately determine the temperature in the steam room, you need to install a thermometer

There are different types of devices on sale - mechanical, electrical, liquid. Studying the features, operating principles, advantages and disadvantages of devices of each type will help you make a choice.

Bath thermometer: types, features. How to choose a thermometer for a bath?

The uniqueness of the bathhouse lies in the fact that it must maintain certain climatic conditions. If the temperature is incorrect or the humidity level is inappropriate, the benefits of the Russian bath will be significantly reduced or completely lost. To maintain an optimal microclimate, some accessories will be useful, in particular, a bath thermometer.

This device is simple and quite cheap, but it will become a faithful assistant in the steam room: the thermometer will warn you about an increase/decrease in the desired temperature, using it you can control the combustion process.

How to install a thermometer in a moonshine still

The correct sequence of actions in this matter is as follows:

1. Choosing a location.

A moonshine still has several zones at different temperatures, which can be monitored to control various aspects of distillation. The main thing is the temperature of the steam.

In this case, the measuring device is installed, if it is the simplest system of a cube, hoses, and a refrigerator, in the upper part of the cube; if the system is more complex and contains elements such as a reflux condenser or a full-fledged distillation column, then the thermometer is also installed in the unit corresponding for rectification, and in the distillation tank.

1. Arrangement of the installation site.

In the selected location, a hole is drilled in the housing to match the diameter of the mounting sleeve, which is used to mount the device.

1. Installing a thermometer on a moonshine still.

When installing the sleeve, a gap is formed between it and the body of the unit; to seal it, you need to use a gasket made of high-quality food-grade silicone. After this, the equipment is fixed in the prescribed manner.

1. Equipment check.

The first time it is better to run the system filled with water. This way it will be possible to check the tightness of the installation site, its ability to withstand pressure and temperature, the adequacy of the device readings, and without risking damage to the raw materials.

The thermometer in a moonshine still is perhaps the most important of the optional parts of the system.

It is difficult to overestimate its influence on the accuracy of “head separation” or “tail cutting”, because each fraction of impurities has an optimal evaporation temperature, by monitoring which you can accurately understand when and what comes out of the refrigerator.

In addition, as the liquid evaporates from the mash, it is important to maintain the correct temperature, which allows both to evaporate the remaining ethanol and not to burn the dry remains of the mash, thereby spoiling some of the raw materials

How to choose a thermometer for a bath and sauna?

The measuring device will be installed in a steam room where there are extreme temperature conditions, as well as high humidity.

Bath thermometers should be:

The most popular bath thermometers are wooden ones, because they meet all the requirements listed above, and also fit perfectly into the interior of a steam room, the walls of which are made of wood or covered with clapboard.

It is not recommended to use a thermometer for a sauna or bath made of synthetic material, since such material, when heated, can release toxic substances that poison the body.

When choosing, also pay attention to the appearance of the thermometer: the scale should be bright and large enough so that the temperature readings can be seen even in a room with a lot of steam.

There is a large selection of measuring instruments for baths, let's take a closer look at them.

Specifics of installing a hygrometer in a steam room

In order for the device’s readings to be as accurate as possible, it is not enough to adjust it; you also need to position it correctly. An alcohol hygrometer-thermometer for saunas and baths is placed at a height of about 1.6 meters, at eye level, opposite the shelf. With this arrangement, monitoring indicators is as convenient as possible.

If dimensions allow, it is advisable to install the device at a distance of 1.5-2 meters from doors, windows and a tray with stones. Sources of heat or cold will interfere with the accuracy of the readings.

When installing the device in a steam room or auxiliary rooms, you need to know the recommended humidity standards in different types of steam rooms and their rooms:

Types of measuring devices

Based on the principle of operation, the following types of thermometers are distinguished:

Each of these measuring instruments has both pros and cons. To make a choice, let's talk about their features.

Dial thermometer for bath

In appearance, such a measuring device is similar to a regular watch with hands, only instead of time the temperature is indicated from 0 to 120°C. Their error is 2-3°C.

The principle of their operation is as follows: a mechanical thermometer has a spring that changes the degree of compression depending on the temperature, thereby causing the needle on the thermometer to change its position.

A mechanical thermometer is a simple and cheap option. There are a huge number of options for the external design of such a device, so choosing a model to suit your taste and design is not a problem.

The main disadvantage of a dial thermometer is low accuracy.

Capillary thermometer for bath

Liquid thermometers provide temperature readings from 0 to 160°C. The error of such devices is about 1°C. They are equipped with a straight tube with any liquid: kerosene, alcohol, toluene, galinstan, there is also mercury, but using it in the steam room is strictly prohibited. Under the influence of temperature, the volume of liquid changes, thereby increasing or decreasing the column.

Capillary thermometers are more accurate than mechanical ones, but in this respect they are inferior to electronic ones.

Electronic bath thermometer

An electronic thermometer is the most modern option and has the highest accuracy. It is a housing made of heat-resistant plastic or stainless steel, with a liquid crystal display.

The range of such a device is also greater than that of other bath thermometers - from 0 to +235°C. It has the lowest error - only 0.5°C.

Some models of electronic thermometers are equipped with a sound sensor that is triggered when a certain temperature is reached.

Electronic devices cannot be installed in the steam room, so in stores you can purchase an electronic bath thermometer with a remote sensor. Its advantage is that in this case the display will not be in the steam room, but in the dressing room or relaxation room; in the steam room itself, it is enough to install a wired or wireless sensor.

The disadvantages of an electronic measuring device are its high cost and the need to periodically change batteries. In addition, for some it will be a minus that you cannot see the temperature directly in the steam room; to do this you need to leave the room and go to the display.

Thermometer with hygrometer for bath

Models equipped with a hygrometer are included in a separate category. A hygrometer for baths and saunas can be purchased separately from the thermometer. It is needed to measure the humidity level in the room, since too high a reading can not only worsen the microclimate in the steam room, but also make it unsafe for health.

A bath hygrometer is a metal frame with a hair or thread running along the vertical axis. The hair is attached to the top of the frame, and a weight is suspended from below. When the humidity level changes, the length of the hair changes and, therefore, the scale indicator.

A thermometer and hygrometer for a bath, sold as a set, are called a bath station. This design can also be additionally equipped with a barometer that determines the pressure in the steam room.

The sauna station allows you to fully control the microclimate of the steam room, but you need to take into account that it is quite expensive, in addition, if one of the devices breaks down, you will have to send the entire set for repair.

Hygrometer for soft steam

In addition to taking into account the temperature, it is necessary to focus on selecting the optimal humidity in the steam room. Steam that contains no more than 30 percent moisture is considered dry and healthy. If this value does not correspond to the standard value, then the soaring procedure will not be effective.

It is worth noting that in Russian baths the air humidity can reach 85 percent, and in washing rooms - 95%. If the bathhouse has a relaxation room, then the humidity level in it should not be allowed to rise above 60% so that the rest is truly relaxing and enjoyable.

The functionality of a hygrometer for baths and saunas is in some sense similar to the operation of a mechanical thermometer. A special thread is installed as a sensor element in such a hygrometer. It lengthens or shortens with fluctuations in humidity, thereby transmitting the necessary information to the device scale. Over time, the sensitivity of the device decreases as the thread weakens, but it can always be adjusted manually.

To configure the bath hygrometer you must use:

• plastic bag;
• kettle;
• a stand for the device of such a size that the device can be placed at the same level as the spout of the kettle.

Sequence for setting up a bath hygrometer:

1. The bag is placed over the device so that the other half is placed over the spout of the kettle. This design can be secured using threads, elastic or twine.
2. Then the device is placed on a stand opposite the spout of the kettle so that the package does not burn.
3. The burner is lit and the kettle is brought to a boil.
4. Then you need to make sure that the device’s arrow reaches the maximum mark and remains there while the water boils (about 3 minutes).
5. If there is a significant deviation from the 100 percent mark, it is necessary to tighten the thread tension using a screwdriver.

If we are talking about setting up a thermometer-hygrometer system for a sauna, then you can also adjust the thermometer. When the kettle is boiling, the temperature should be between 97 and 100 degrees Celsius.

Classification of medical thermometers

Human senses cannot determine temperature with the necessary accuracy. For this purpose, special devices have been created that contain substances or materials that are sensitive to heating or cooling. It is by their reaction or state that one or another temperature value of the environment is judged.

The following types of thermometers are most often used in domestic conditions:

• mercury;
• electronic;
• infrared;
• thermal strips.

Each of them deserves a separate description. You can figure out which thermometer shows temperature more accurately - mercury or electronic - by comparing their design and technical characteristics. They depend on the measurement method and the build quality of the device.

Mercury thermometer

The action of a mercury thermometer is based on the property of a liquid to change its volume depending on temperature. Its main working element is a sealed glass container partially filled with mercury. One end of it is made in the form of a thin capillary, along which, when heated, the boundary of the liquid metal moves.

Only the edge of the flask containing the bulk of the mercury comes into direct contact with the body. To reduce the influence of the environment on the quality of measurements, the capillary is placed in a tube with a vacuum.

Mercury thermometer gives accurate readings

The scale located next to the capillary shows the temperature quite accurately. For ease of observation, mirror strips are inserted into the thermometer, visually increasing the thickness of the mercury column. A special feature of medical thermometers is the local narrowing of the glass tube, which prevents the liquid from returning to the main container during cooling. This allows you to determine the maximum reached, but requires shaking the device after use.

Important! Mercury thermometers have a fragile structure and require careful handling. You need to be especially careful when measuring temperature in children

FASTEST

Despite the higher price compared to traditional mercury thermometers, which starts from 350 rubles, and the need to change the battery from time to time, electronic thermometers are currently considered optimal in terms of safety and quality.

However, often the simple procedure of measuring temperature can become a problem - holding the thermometer under the armpit of a restless child for as long as 7-10 minutes becomes an impossible task for parents.

In this case, the most technologically advanced temperature measuring device available today will help - a non-contact infrared thermometer. Unlike an electronic thermometer, which takes measurements using a temperature sensor, a non-contact device reads infrared radiation from the human body.

“When using an infrared thermometer, there are some nuances,” says Olga Babich. “After turning it on for the first time, you need to let it run for about five minutes so that it “feels” the temperature of the room.”

According to her, if a person is sweating, it is necessary to dry off, as wet skin will lead to incorrect measurements. Moreover, the measurement itself, for which the forehead is usually used, lasts only two seconds, which makes such a device very convenient for small children.

“By the way, an infrared thermometer is convenient because it can measure not only body temperature - if necessary, it will show the temperature of the room or, say, wine,” continues the interlocutor.

The main disadvantage of non-contact thermometers is the high price, which averages 3 thousand rubles. Despite this, the demand for them is now the highest, since they are really very convenient, the expert says.

Temperature measuring instruments

In thermometry, a special measuring device is used - a thermometer to measure body temperature. These devices are also called thermometers. They are made from different materials (glass, plastic), have their own specifics and operating principle (contact, non-contact; digital, mercury, infrared), and measurement error. Each type of these devices has its own advantages and disadvantages.

Classification of devices

The main principle by which thermometers for measuring body temperature are classified is the principle of operation of these measuring instruments. According to it they are divided into:

• mercury;
• digital;
• infrared (for non-contact measurement method).

Mercury thermometers are made of glass and work on the principle of expansion of mercury contained in their glass reservoir. When heated from the body, the mercury column moves up the scale, reaching a mark corresponding to the t temperature of the body. This method of determining temperature characteristics helps to obtain high accuracy of measurement results; the error in actual temperature when using this type of thermometer is only 0.1 degrees.

• fragility of the body;
• mercury toxicity (there is a danger of poisoning if you accidentally damage a mercury tank or break a thermometer);
• measurement duration (up to 10 minutes).

Digital, electronic thermometers are widely used. They can have a different appearance, their body is made of plastic, and the temperature is determined through the operation of a thermodynamic sensor. Electronic thermometers are safer than mercury thermometers and help to obtain quick measurement results (within one minute), however, the accuracy of the readings of these devices is significantly inferior to mercury thermometers.

Infrared devices for measuring temperature indicators do not require direct contact with the body; measuring the temperature value takes several seconds. A special sensor displays a digital infrared image; the device requires configuration, produces an error of about 0.2 degrees, is expensive, and is often used in cases where the patient cannot be disturbed.

Especially for infants who cannot remain at rest for a long time, nipple thermometers disguised as a regular pacifier have been invented. They are made from silicone, the measurement duration is about five minutes, but this does not bring any inconvenience to the child. The deviation from the exact data can reach 0.3 degrees.

Installation recommendations

How to install a thermometer yourself, but at the same time do it correctly? In order to properly mount a thermometer on a moonshine still, you need to perform a series of sequential steps. First, decide on its location: as a rule, it is placed near the pressure gauge. If your moonshine still is made at home, then the best place to place the thermometer is the lid of the still.

Drill a hole of the required diameter in it, then install a seat for the device in the hole (usually included in the kit), where the thermometer will be placed in the future. After this work has been done, the structure must be fastened with a bolt to the outside of the distillation cube. Now everything is tightened together with a fixing nut, and the device is mounted inside the landing cylinder. Before starting the moonshine still, it is necessary to check it.

To do this, you need to fill two-thirds of the cube with plain water and begin the distillation procedure. Use the device to monitor the temperature readings. We try to adjust such data as the stability and accuracy of indicators, the tightness of connections. If the test results were successful and the distillation temperature remains within 19−20 °C, feel free to start distilling the mash. If the outlet water temperature exceeds the norm, the cooling system most likely needs to be modified.

Now you know all the main points regarding the thermometer that is installed on the moonshine still. Whether you need this device and which model to give preference to, decide for yourself, but remember, you can only get high-quality moonshine with experience, good equipment and knowledge of what you are doing.
