Room sensor KWL-VOC eC
Any use other than the intended use is prohibited!
1.8 Functionality
The air quality is detected by KWL-VOC eC (mixed gas sensor for volatile organic
substances). This sensor determines the loading of the room air due to contami-
nated gases such as cigarette smoke, body perspiration, exhaled breathing air,
solvent vapours, emissions, etc.

The recommended installation height for the room sensor KWL-VOC eC is between
1.4 and 1.5 m, persons who are usually standing and sitting are considered equally
at this height.
The room sensor KWL-VOC eC can also be installed at a different height if the specific
spatial conditions do not allow the recommended installation height.
