Rating of the best thermometers for baths and saunas for 2021

The most important condition for maintaining a comfortable temperature in a bath or sauna is the presence of a hygro-thermometer.

In our review, we will provide advice on how to choose the right product with high measurement accuracy, identify the best manufacturers, guide you by the average price, and give recommendations on what you should pay attention to so as not to make a mistake when choosing.

What are they for?

Such measuring instruments are designed to control temperature, regulate air humidity in the sauna, so that there is no overheating and vice versa. They are necessary to create a safe, proper microclimate, which is important for people who prefer to steam at specific temperatures.

It is correct to hang the device 15 cm below the ceiling directly above the heater.

Another useful item is a hygrometer. It indicates the humidity, which usually ranges from 10% to 35%, depending on the amount of water used in the steam generator.

High temperature combined with high humidity is an aggressive environment for human health. The hygrometer, at 100 – 110 ͦ C, should show no more than 30%, at 60 ͦ C and below, the reading is 85%. Fluctuations in water vapor in the air can cause diseases, so you should take seriously the criteria for choosing equipment, its functionality, features, and permissible measurement errors.

Pros and cons of sauna stations

Purchasing control and measuring instruments as a set will eliminate a lot of hassle in selecting an equivalent design for individual devices. On a single, impressively designed station panel, a different set of instruments can be located: from two main ones to all four. The type of measuring devices and their number depend on the location of the upcoming operation and the preferences of the owner:

• a bath station with an hourglass is purchased to equip steam rooms;
• electronic and mechanical complexes with barometers and clocks are purchased for installation in locker rooms and rest rooms;
• digital stations with a temperature sensor are installed outside, not far from the steam room, and the measuring organ is brought into the room being tested.

The only disadvantage of a set of devices is that if one device breaks down, you will have to carry everything for repair.

After completing a detailed review of control devices, there will certainly be no doubt about their necessity. You can purchase a full set of instruments or limit yourself to purchasing a thermometer and a watch. It is important not to forget: controlling the parameters of the bath microclimate will ensure ideal results and protect against negative consequences.

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.

It is important to note that the price of this unit is much higher than inexpensive devices with arrows or capillary ones, this is justified by the build quality and wear resistance. The machine can work at 115 ͦ C, but don't worry that it will suddenly melt, the product is made of high-strength, heat-resistant material, stainless steel.

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.

Electronic, dial thermometers and hygrometers for the steam room

All thermometers presented today have common features and distinctive features. They differ in size and shape, as well as in the presence of separate sensor windows or their combination. In addition, the material from which the cases are made plays a role. As a rule, this is the same tree that is used to arrange a steam room, namely the usual: cedar, aspen, pine, birch. All these rocks are characterized by low heat capacity and durability in conditions of heat and moisture. Wood with other properties is not used for arranging steam rooms and for the manufacture of accessories and devices for them.

How to choose a quality product

When buying a thermometer, the first thing you should pay attention to is the body. The device must have a sealed, safe casing that can withstand high temperatures and high humidity. The best option is the one made of wood. Low thermal conductivity prevents accidental fire.

All transparent structural elements must be made of heat-resistant glass. It is also important to consider the range of readings. Ideally, a hygrometer should be able to show from 0% to 100%, with a thermometer above 100 °C. It is important to purchase certified products only from a reliable manufacturer - a guarantee of successful operation of the device for a long time.

Installation of a hygrothermometer in a sauna, bathhouse

You must make sure that the device is at a height of 1.6 m above the ground, at least 1.5 m from the door, windows, stove. Sources of heat and cold can influence readings and be misleading. When installing the product, you must know the recommended humidity levels for each type of sauna and adjacent rooms:

• Russian bath: humidity from 75 to 85%, temperature from 60 to 70 ° C;
• Turkish sauna (hamam): 95 - 100%, 70 - 100 °C;
• Finnish (dry): 25% - 35%, 100 - 110 °C;
• toilet room: 90 - 100%, 30 - 40 °C.
• hall: from 30 - 60%, 20 - 25 °C.

Providing these conditions will make your stay in the bathhouse comfortable, enjoyable, and most importantly, beneficial for your health.

Bath barometer

The air pressure in the steam compartment is also a very important parameter, which some bath attendants do not pay enough attention to. Indeed, temperature and humidity are fundamental parameters, but optimal pressure is also very important if the bath attendant wants to create the most comfortable conditions for his visitors.

If we are talking about a Russian bath, then there is no need to use a barometer in the steam compartment, and optimal pressure should be achieved within the rest room. The use of mercury barometers is strictly prohibited due to safety regulations.

The simplest and most suitable for use in a bathhouse is the aneroid. This device is in the form of a regular box with corrugated walls. If the pressure decreases, the box expands and vice versa.

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.

Bath timer

Bath procedures are a responsible process. The consequences that may arise in the event of an extremely long stay in conditions of elevated temperature have already been described above. In the steam room, to record the time spent in the room, you can install both a simple hourglass and an electronic clock.

Naturally, an electronic device cannot be installed in a steam room, but if it is installed correctly, you can get an originally designed accessory with increased practicality during operation. In the photo and upon visual inspection, such an element will look very beautiful and will create an atmosphere of modernity and technology in the room.

Bath thermometer

Not a single experienced bath attendant can say with confidence that his many years of experience will allow him to regulate the temperature in the steam room more accurately than when using an electronic thermometer for baths and saunas. Each visitor to such establishments has his own limit for the body’s temperature sensitivity.

For various types of baths and saunas, optimal temperature limits for receiving procedures have been established:

• in a Russian bath they range from 40 to 60 degrees Celsius;
• in Turkish - similarly;
• in a Finnish sauna – 100-110 degrees Celsius. The reason for such high heating is that the human body tolerates dry steam much more easily than wet steam.

The temperature is determined by visitors in advance if they have established preferences, or is selected as the steam room heats up. By constantly checking the thermometer for the steam room, you can choose the optimal temperature. If there is overheating, it will be enough to ventilate the room, but in this case you will have to reschedule the paired procedures until the optimal temperature is established.

In private and commercial buildings, a simple mechanical or electronic bath thermometer with an external temperature sensor is used. Standard mechanical devices operate on the principle of thermal expansion of bodies. The body that is sealed into such a thermometer for a steam room can be presented in any state of aggregation - from gas to a solid structure.

If we are talking about a gas thermometer for a sauna, then it is worth noting its high error and the widest range of temperature values, which makes its use impractical. Such devices have a low price and a simple design.

The best electronic thermometer for a sauna with a remote sensor detects changes in temperature conditions through a proportional change in the resistance of the conductor in the structure. Naturally, modern electrical devices are an order of magnitude more expensive, but the accuracy of the measurements they make is significant.

Typically, electronics of this type are produced in the form of universal devices, which include not only a thermometer, but also other measuring instruments.

The most common devices for installation in a bathhouse:

• liquid thermometer - with a working container in the form of a flask. A narrow test tube with a special liquid and a marked scale are placed inside such a container. With temperature changes, the liquid column increases or decreases as it expands or vice versa. The value opposite which the upper limit of the column is set is the room temperature;
• a dial thermometer is the same mechanical thermometer as a liquid one, but its significant difference is the iron-nickel spring. When the air temperature changes, the spring itself increases and contracts, which in turn affects the mechanical needle. The arrow moves along a circular scale and, stopping at a certain value, indicates the temperature inside the room;
• An electronic thermometer is the most modern and most accurate device, in which a special sensor acts as a functional temperature meter. As a result of its work, an electronic sauna thermometer displays all received data on a graphic display. The positive quality of this device is its highest accuracy. However, an electronic thermometer for baths and saunas has a significant drawback - it cannot be installed directly in the steam room. Based on this drawback, it becomes difficult to install an electronic thermometer. It is necessary to ensure that the sensor from the electronic thermometer is placed in the steam room, and the device itself is placed in the next room. For this purpose, a meter cable is used, provided in the basic configuration of the device. Naturally, difficulties arise in monitoring the temperature in the room on the part of visitors taking bath procedures.

Based on the foregoing, we can conclude that it is best to install a pointer or liquid version of the device in a steam room. If we are talking about a private sauna, where all the wishes of the clients are satisfied by the bathhouse attendant, then you can use an external sauna thermometer if there is a permanent operator monitoring the readings of the device.
