CO2 Combustible Fixed Gas Detector

The Carbon Dioxide (CO₂) Combustible Fixed Gas Detector (PX2-1-2-I464-C-01) continuously monitors CO₂ levels from 0 to 5000 ppm and vapors in 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.
