The Carbon dioxide sensors from the CO2 series monitors carbon dioxide from 0 to 2000 ppm for wall and duct mount applications. They feature analogue outputs with a patented ABC Logic™ self-calibration system. The concentration of carbon dioxide is measured using a Single Beam, Non-Dispersive Infrared (NDIR) Absorption sensing method. Room units feature the option of multi-colored LEDs. They will indicate one of five approximate ppm levels. These units should not be used in environments such as greenhouses, wineries, breweries. They should also be avoided in areas where industrial sources of carbon dioxide are present or in applications where the space is left unoccupied for less than 4 hours a day. Features & Benefits:

Multi-colored LEDs
