Rating of the best thermometers for baths and saunas for 2022

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, orient at an average price, give recommendations on what you should pay attention to so as not to make a mistake when choosing.

What do you need

Such measuring devices are designed to control the temperature, regulate the 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 bathe at specific temperatures.

It would be 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 readings are 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.

Types of devices

Consider a few popular models. They can be mercury (capillary), pointer, electronic and complex, which combine several devices (hygrometer, barometer, clock):

• Electronic (digital)

The device has a remote temperature sensor, LCD monitor, meets all European standards. The product is considered the most modern, advanced, ideally fits into the interior of the bath space. The error of indications is half a degree, it is characterized by increased reliability.

It is important to note that at a price 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 do not worry that it will melt suddenly, 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 (pointer)

The unit is often used in saunas. This is a budget, 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 bath with shelves made of solid Karelian birch. The product is highly durable. The disadvantage of the device is the high error in the readings of t ° C.

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

• Capillary thermometer

According to the principle of operation, it does not differ from a conventional thermometer. Its design feature is a glass flask consisting of high-strength glass.

The advantage of a mercury appliance is an attractive appearance, combined with the classic interior of a Russian bath. A serious disadvantage of the device is the increased likelihood of mercury evaporation when it breaks, which can be harmful to health, especially at high t ° C, humidity in the sauna.

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

• bath station

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

How to choose a quality product

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

All transparent structural elements must be made of heat-resistant glass. It is also important to consider the range of indications. Ideally, the 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.

Which brand of device is better to buy

Top level instruments are available from Harvia, Sawo, Wendox, Moller, Nevsky Banshik, Tylo, Eos. Buying any of these guarantees a great product, although good quality hygrometers can be purchased from lesser known companies. A branded meter will cost more, it is of better quality, more durable. There are exclusive products with wood carvings.

Installation of a hygrothermometer in a sauna, bath

You must make sure that the appliance is at a height of 1.6 m above the ground, at least 1.5 m from the door, windows, stove. Sources of heat, cold can affect the readings, mislead. When installing the product, you need to 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 (hammam): 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 ° С.

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

Additional accessories

As we said above, in addition to the hygrothermometer, a barometer can be installed 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 spent in the steam room - the optimal time should be no more than 15 minutes.

Where could I buy

To learn about the latest innovations, consult with managers which device is better to buy, decide on the functions of the model you like, visit the nearest specialized salon. You can also go to the online store by ordering the product online.
