IMR EX440 SMART sensor gas detector

IMR EX440 SMART sensor gas detector

The detector uses natural diffusion as the method to detect gas. It is constructed with high strength engineering plastics composites with an antiskid rubber housing. The detector is comfortable to hold, is water-proof, and dust-proof.


  • Intrinsically safe
  • Smart interchangeable module
  • Catalytic, electrochemical, infrared, PID sensor selectable
  • Built-in pump optional
  • Storage for 100,000 detection records
  • Calibration point adjustable
  • Two alarm levels for each channel
  • STEL & TWA alarm for toxic gases
  • Visual, audible, and vibration alarms
  • Data uploading
  • Password management
  • Self-test when power on
  • Modular design for ease of maintenance


The IMR EX440 portable multi gas detector is an intrinsically safe instrument that can continuously detect the concentration of combustible gases and toxic gases. It is designed for use in explosion proof, toxic gas leak rescue, underground pipeline or mines, and other hazardous locations. It effectively ensures the safety of staff life without being invasive and prevents loss of production equipment.
