The Air Quality Meter is specially designed for long-term monitoring of climatic conditions in, for example, offices, classrooms or lecture halls. The Air Quality Meter has various sensors. Among other things, the Air Quality Meter has a carbon dioxide sensor up to 40,000 ppm, a temperature sensor with a measuring range between 0 ... 50 °C, an ambient humidity sensor with a measuring range between 0 ... 100% RH and a barometer with a measuring range between 300 ... 2000 hPa.

The Air Quality Meter can therefore be used in many applications due to its large number of sensors. The measured values are shown directly on the e-paper display of the air quality measuring device. A good / medium / bad rating of the carbon dioxide content in the ambient air is also displayed.
