With our wet-bulb temperature calculator, you can easily calculate the wet-bulb temperature for a given air temperature and relative humidity, and thus determine the heat stress on the body or the maximum cooling capacity of the air.
What does the wet-bulb temperature indicate?
The wet-bulb temperature is the lowest temperature that can be achieved through the evaporation of water—the drier the air, the lower it is than the normal air temperature. It thus indicates the cooling potential available through evaporation in the air and is important, for example, for evaporative cooling, cooling towers, and the assessment of heat stress.
We are continuing to work on improving the air-Q wet-bulb temperature calculator and welcome any requests or suggestions for improvement.

In addition to the smartphone app and web app, air-Q science (AQ-Science) offers additional functions via the air‑Q API. This allows access to developer functions. It also opens up all possibilities for self-developed smart home applications. An individual, high-quality additional sensor can be selected as an option.

The air-Q radon contains our self-developed radon sensor. This measures to the highest standards with unsurpassed accuracy and response time. The air-Q radon also includes some basic additional sensors to monitor the indoor climate. As with all air-Qs with free smartphone app and web app and fully customizable LED themes and acoustic signals. The air-Q radon is available in different versions with Science Option and various additional sensors.

The air-Q radon science includes our self-developed radon sensor and other essential air quality sensors. As with all air-Qs, the free smartphone app and web app are also included.
