CO₂ Room Sensor with Temperature
NSA-CO2-ROOM

Part Numbers

NSA-HH/CO2-R2-CP-C
NSA-HH/CO2-R2O-CP-C
NSA-HH/CO2-R2SO-CP-C

The Carrier Carbon Dioxide Room Series Sensor with Temperature, Setpoint, and Override monitors the carbon dioxide (CO₂) levels in commercial, school, and office-type environments. The concentration of CO₂ is a strong indication of the overall indoor air quality. The NSA-HH/CO2-R2 Series is based on a single beam, non-dispersive infrared technology and is a cost-efficient solution for measuring carbon dioxide levels for building climate control. In addition, ABC software eliminates the need for manual calibration. Carbon Dioxide concentration is measured up to 2,000 ppm and is converted into proportional analog outputs.
