A/CO2-T-RSO

The A/CO2-T transmitters monitor both the temperature and carbon dioxide (CO2) levels in industrial and living environments. The concentration of CO2 is a good indication of the indoor air quality (IAQ).

All units come with both a 4-20 mA and a 0-10 VDC analog output for CO2 and a resistive type temperature sensor. The temperature sensor is available with options including Override, Setpoint, and a RJ-14 Communication Jack. By combining both the temperature and CO2 sensors in one package, installation and maintenance is greatly simplified.

The concentration of CO2 is measured using a Single Beam Absorption Infrared Diffusion sampling method. The CO2 transmitter is also equipped with a patented ABC LogicTM (Automatic Background Calibration) software. The ABC LogicTM software virtually eliminates the need for manual calibration in applications where the indoor CO2 level drops to outside levels during unoccupied periods. The ABC LogicTM will not work properly in applications where the space is left unoccupied for less than 4 hours per day or where there are industrial sources of carbon dioxide.
