CO AND NO2

Carbon Monoxide & Nitrogen Dioxide Sensors

The CO and NO2 Series transmitters monitor carbon monoxide, or nitrogen dioxide, and are designed
for the continuous monitoring of vehicle exhaust in non-hazardous areas. A wide spectrum, long life
electrochemical sensor measures the amount of carbon monoxide or nitrogen dioxide in the environment.
Both the Room and Duct transmitters are offered in a standard NEMA 1 rated ABS Polycarbonate plastic
enclosure. An optional NEMA 4X watertight and dust proof enclosure is available with the room transmitter.
Other options include an LCD display with (2) SPDT Form 1C relays and a buzzer.
