Immission measurement
Our portfolio includes devices for monitoring the air quality at outdoor areas, in buildings and at workshops.
The measuring devices have been developed for year-round use indoors as well as outdoors. They are factory-calibrated under the highest quality requirements.
The suitability for monitoring nitrogen dioxide in the outside air and at the workplace has been proven with comparative measurements in the field at a certified air quality measuring station by third parties (Karlsruhe Institute of Technology).
