The QPM2102 channel sensor from the STANDARD series is used for measuring air quality in ducts and channels. The sensor monitors the levels of CO2 and VOC in the airflow within ventilation or air conditioning systems. The sensing is based on the principle of optical infrared absorption measurement (CO2) and the principle of a heated zinc oxide semiconductor (VOC). The sensors can be used to regulate supply or exhaust air or as components of a building management system. The sensor is ideally suited for rooms where a large number of people gather and where there may be increased indications of fumes and undesirable concentrations of various odours. This may include schools, conference halls, auditoriums, cultural social facilities, schools, canteens, restaurants, and more.

This sensor is not intended as a warning safety signal for smoke or gas leaks. Additionally, the sensors are not designed for outdoor use.
