The Carbon Dioxide (CO2) Combustible Fixed Gas Detector (PX2-1-2-I464-C-01) continuously monitors CO2 levels from 0 to 5000 ppm and vaporsin hazardous zones 1 and 2.
This explosion-proof fixed CO2 detector features a 4-20 mA/RS485 Modbus output, alarm, and fault relays. It is also SIL2 certified, making it suitable for monitoring toxic gases in ambient air.
The detector is well-suited for industries requiring protection from hazardous CO2 gases, such as laboratories, boiler rooms, combustion control rooms, confined spaces, garages, gas stations, process rooms, and refineries.
This device is also frequently used in cryogenic facilities, dry ice freezing, factories, industrial, nitrogen applications, and more.
