Asense CO2 8322 Duct Sensor NSA-ASENSE-CO2-DUCT Carrier Air Quality and Leak Detection Air Conditioner Sensor


Part Numbers

NSA-ASENSE-D-LCD-REL
NSA-ASENSE-D-REL

The ASENSE Duct series with IP65 Rated Enclosure monitors the carbon dioxide (CO₂) levels in industrial, commercial, school, and office type environments. The concentration of CO₂ is a strong indication of the overall indoor air quality. The ASENSE Series is based on a single beam non-dispersive infrared technology and is a cost-optimized solution for the climate control of buildings and other processes. In addition, ABC software eliminates the need for manual calibration. The ASENSE Series measures the CO₂ concentration in the ambient air up to 2,000 ppm and converts the data into an analog output.
