The QPM2102D 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 flowing air in 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 elements of a building management system. The sensor is ideally suited for rooms where a larger number of people gather and where there may be an increased indication of fumes and undesirable concentrations of various odors. This can include schools, conference halls, auditoriums, cultural social facilities, schools, canteens, restaurants, and more.

This model features an integrated display. The display shows the currently measured data. In this case, CO2 and VOC are displayed as a bar graph.

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