The A/CO2 transmitters monitor carbon dioxide (CO2) levels in industrial and living environments from 0 to 10,000 ppm. The concentration of CO2 is a good indication of the indoor air quality (IAQ). All units come with both a 4-20 mA and 0-10 VDC analog output as well as a relay output with an adjustable setpoint and deadbank (Hysteresis). An optional LCD display may be added to the room unit while all the duct configurations come standard with the LCD display. The concentration of CO2 is measured using a Single Beam Absorption Infrared sensing 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 a day or where there are industrial sources of CO2. The room transmitter is encased in a white enclosure while the duct sensor is enclosed in a black case that is UL94-5V rated and includes a pitot tube. All units come with a two year factory warranty.
