DUCT AIR QUALITY (VOC) AND CO2 SENSOR KLQ-CO2-MB
Maintenance-free duct sensor covering air quality (VOC 0…100 %), carbon
dioxide (CO2 0...5000 ppm) and atmospheric pressure (hPa). The air
quality is detected by a VOC sensor (mixed gas sensor for volatile
organic substances) and include an automatic calibration. It determines
the loading of the room air due to contaminated gases such as cigarette
smoke, body perspiration, exhaled breathing air, solvent vapors,
emissions etc. The air contamination can be selected into different
sensitivity ranges as low, medium or high. The CO2 measurement is
performed using an optical NDIR sensor (non-dispersive infra-red
technology), and the detection range is calibrated for standard
applications such as monitoring residential rooms and conference rooms.
A microprocessor-controlled solution with factory sensor calibration,
Modbus RTU connection in a resistant IP65 plastic housing with mounting
flange, quick-locking screws and two M16 cable gland for cable
connection. International SI units (default) can be changed to imperial
