Honeywell AQS71-KAM-T Duct Sensor for measuring temperature and CO2 concentration in ducts. The sensor is based on the principle of an infrared beam. A calibration-free process compensates for the aging of the infrared source and ensures excellent long-term stability. The sensor provides a 0…10 V analogue output for CO2 and temperature and is designed for HVAC applications.
