Airflow Sensor KLQ CO2 & Air Quality

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 (via Modbus). VOC Sensor: Volatile Organic Compounds sensor (metal oxide) with automatic calibration VOC measuring range: 0…100 % air quality; referred to calibrating gas temperature dependence: ± 5 ppm pro °C or ± 0,5 % of measured value pro °C (whichever is higher) pressure dependence: ± 0.13 % per mm Hg Medium: clean air and non-aggressive, non-combustible gases Power: 24VAC/DC (± 10%) 24DC <1,6W Operation temperature: –10...+60 °C / 14...+140 °F T2-IP65 plastic housing two M20 cable glands Housing dimensions: 126 x 90 x 50 mm / 4.96 x 3.54 x 1.97 in
