NSA-ASENSE-R-LCD
The ASENSE Room Sensor series 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 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.
