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. The factory default output is 4-20 mA, whereas 0-5 VDC and 0-10 VDC outputs are able to be field selected via integral dip switches. Thermistor temperature outputs, along with setpoint and override, are available as options for room configurations. The A/CO2 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. The A/CO2 Series is covered by ACI's Five (5) Year Limited Warranty. Carbon Dioxide sensors or transmitters for HVAC, Building Automation Systems, or ANSI/ASHRAE Standard 62.1 2007. Typical applications include: schools, office buildings, auditoriums, gymnasiums, shopping malls, theatres, Demand Control Ventilation, or economizers.
