A/CO2-VEN

The A/CO2 -VEN series monitors carbon dioxide (CO2) levels in industrial and living environments from 0 to 2,000 ppm. (Additional ranges can be requested-Please contact ACI for further details) The concentration of CO2 is a good indication of the indoor air quality (IAQ). This series offers the installation flexibility of adding analog relative humidity and temperature sensors in a single wall-mounted enclosure.

The A/CO2-VEN series offers increased flexibility in other areas as well. The enclosure is offered in either white or black and has a locking screw to secure the cover. It offers multiple analog outputs of 4 to 20 mA, 0 to 5 VDC, and 0 to10 VDC. There is also an optional LCD available for certain models. (See ordering information on the pdf cut sheet)

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.
