How to Choose a Good Thermometer for the Sauna?

Having a thermometer in the sauna is a must because it’s a matter of safety knowing the level of both temperature and humidity reached inside the sauna. Even if your sauna has its built-in digital controller with a thermometer, it’s useful to have your own unit inside the sauna because the digital controllers of the saunas are usually placed outside and the readings are not very accurate. If your sauna doesn’t include one, it’s up to you to buy a thermometer that will help you monitor the ambiance during your sauna session. Take our advice when looking for a thermometer for your sauna and you will be very pleased with your purchase.

• There are two types of thermometers available on the market, namely digital and analogical. For use in the sauna, we recommend the analogical ones that are more resistant to high temperatures and are not prone to shortcuts.
• If you want to buy only one unit, you should go for a thermometer that measures both temperature and humidity. It’s true that not every model is designed like this and if a thermometer measures only the temperature, it’s not necessarily a poorer unit. However, one that reads both parameters is more useful and practical.
• For increased convenience, the sauna thermometer should display readings in both Celsius and Fahrenheit degrees. This way, you will be able to get the hang of a sauna that displays only Fahrenheit temperatures, in case you live in an area where you use Celsius.
• Buy a thermometer with a large dial so you will clearly see the numbers without having to come close or open the sauna door. A model with a 5 or 6 inches dial will provide perfect visibility.
• Although more of an aesthetic aspect, the material of the housing can also be a matter of durability and resistance to high heat and humidity levels. Therefore, it’s advisable to look for units made of stainless steel or a resistant type of wood like cedar.
• When installing the thermometer, it’s vital that you place it at head level relative to sitting height to enable it to make the proper readings. If you place it too high, it will get very high readings as heat tends to elevate while placing it too low could lead to measuring a low temperature.
