A/CO2-010-R

The A/CO2-010 room and duct transmitters monitor the carbon dioxide (CO2) levels in industrial and office type environments. The concentration of CO2 is a good indication of the overall indoor air quality (IAQ). All units come with a 0-10 VDC analog output as well as the patented ABC LogicTM self-calibration system (Automatic Background Calibration). The concentration of CO2 is measured using a Single Beam Absorption Infrared Diffusion or Flow Through sampling method depending on the mounting configuration.

The ABC LogicTM software eliminates the need for manual calibration in applications where the indoor CO2 level drops to outside levels during unoccupied periods (ie. During evening hours). Also the ABC LogicTM will not work properly in applications where the space is left unoccupied for less than 4 hours a day or where there are industrial sources of CO2 present. An optional three color LED is available for CO2 level indication on the room version only. All room units include a 20K NTC thermistor for monitoring the room temperature.
