  • The ACI CO2 (A/CO2 R2) room transmitter monitors the carbon dioxide (CO2) levels in industrial, school, and office type environments
  • The concentration of CO2 is a strong indication of the overall indoor air quality
  • The A/CO2 Series is based on a single beam, non dispersive infrared technology and is a cost efficient solution for measuring carbon dioxide (CO2) 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
  • 4-20 mA, 0-5 VDC and 0-10 VDC outputs are field selectable
