Hydrogen Gas Detector - PX2

  • High accuracy, linearity, repeatability, and stability
  • Extremely resistant to poisoning
  • Long lifetime of up to 15+ years

Add to compare

The Gas Detector PX2 is a fixed, microprocessor-based gas detector designed for continuous monitoring of ambient air to detect combustible gases and refrigerants in hazardous areas, specifically zones 1 and 2. It features a powerful MPS™ sensor element with integrated temperature, humidity, and pressure compensation, ensuring high accuracy, selectivity, and reliability. The sensor is resistant to poisoning, has a long lifespan of up to 15+ years, and includes self-monitoring capabilities. The device offers a 4–20 mA/RS-485 Modbus output signal, alarm and fault relay, and an optional LC display with status LEDs. It is compatible with PolyGard® gas controllers and other automation systems, making it suitable for industrial and commercial applications such as oil/gas industry, biogas plants, petrochemical industry, power plants, and gas transfer stations.
