Rating of the best thermometers for baths and saunas for 2024

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, orientate at an average price, give recommendations on what to look for in order not to make a mistake when choosing.

What are we for

Such measuring devices 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, correct microclimate, which is important for people who prefer to steam at specific temperatures.

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

Another useful item is a hygrometer. It indicates the moisture content, 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. A hygrometer, at 100 - 110 ͦ C, should show no more than 30%, at 60 ͦ C and below, the reading is 85%. Oscillations of water vapor in the air can cause disease, so you should take seriously the criteria for choosing equipment, its functionality, features, and permissible measurement errors.

Varieties of devices

Let's consider several 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, and will ideally fit into the interior of the sauna space. The reading error is half a degree, it is highly reliable.

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 durability. The machine can work at 115 ͦ C, but don't worry about it melting 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 (switch)

The unit is often used in saunas. It is a budget, easy-to-use, stylish device with a bright scale, showing reasonably 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 of the t ° C readings.

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

• Capillary thermometer

The principle of operation does not differ from a conventional thermometer. Its design feature is a glass bulb made of high-strength glass.

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

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

• Bath station

Another comprehensive solution for microclimate control is a sauna station. This equipment includes a thermo-hygrometer, a barometer. All measurements are displayed on separate sections of the display, which makes the acceptance of procedures even more comfortable. 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 enclosure 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, a hygrometer should be able to read 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 company is the best device to buy

Highest level instruments are available from Harvia, Sawo, Wendox, Moller, Nevsky Banshik, Tylo, Eos. Buying any of these guarantees a great product, although good quality hygrothermometers can be bought from less established companies. A branded meter will cost more, it is of higher quality and more durable. There are also exclusive wood carvings.

Installation of a hygrothermometer in a sauna, steam bath

You must make sure that the device is 1.6 m above the ground, at least 1.5 m from the door, windows, stove. Sources of heat and cold can affect readings and be misleading. When installing the product, it is necessary 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 ° С;
• Turkish sauna (hamam): 95 - 100%, 70 - 100 ° С;
• Finnish (dry): 25% - 35%, 100 - 110 ° С;
• toilet room: 90 - 100%, 30 - 40 ° C.
• hall: from 30 - 60%, 20 - 25 ° С.

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

Optional accessories

As we said above, in addition to a hygrothermometer, a barometer can be installed in the steam room, which measures the pressure in the room. This equipment is useful for people with heart ailments. Please note that cheap barometers are not capable of timely displaying sudden pressure changes, so if you need this indicator, it is recommended to install a quality instrument.

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

Where can I buy
