CO2 ROOM Sensor

  • The ACI Carbon Dioxide Room Series (A/CO2-R2) 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 A/CO2 Series is based on a single beam, nondispersive 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
  • Thermistor temperature outputs, along with setpoint and override, are available as options for this configuration as well
  • Please see the order grid for the available sensor options
  • The A/CO2-R2 Series 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
