Anwendung
Our duct air quality sensor is used to measure the air quality in ventilation ducts of technical systems and the values can be output via a Modbus connection. The sensor used in the duct air quality sensor is a VOC/mixed gas sensor. CO2 equivalents can be derived using a corresponding algorithm, as the odor emissions overlay the CO2 value (see graphic). Long-term drift and operational aging of the duct air quality sensor can be eliminated by regular automatic calibration.
