Additional information

Applications :

The VOC-8… air quality sensors measure the concentration of multiple gases
and odorous substances in the air with constant output. These substances, for
example, may be tobacco smoke, kitchen vapors, human odors and unpleasant
smells. In conjunction with a control device, it controls the fresh air supply
according to the quality of the air in the room; as a result, energy savings
can be made. In combination with a measurement device, it provides an
indication of air quality in the room
