The ACI Carbon Dioxide Duct Series (A/CO2-D) 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 A/CO2 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
  • The factory default outputs are 0-10 VDC (Output 1) and 4-20 mA (Output 2), whereas 0-5 VDC is field selectable via integral dip switches
  • The A/CO2-D provides data which can be used in conjunction with a Building Automation System or Demand Control Ventilation to decrease energy consumption while creating a healthier indoor climate
