IMR 8000 Open Path Infrared Gas Detector

IMR 8000 Open Path Infrared Gas Detector

Open Path Laser Methane Gas Detector/Analyzers are widely used in industrial gas detection fields such as

  • LNG/LPG cylinder factory
  • Petroleum Refinery
  • Offshore oil and gas platform
  • gas plant
  • gas pipelines
  • tunnel engineering


The IMR 8000 uses advanced TDLAS technology to detect gas concentrations in an open space by the absorption of specific light wavelengths by gas. The system is designed to keep your personnel safe in high risk environments. It can detect CH4 over distances of 120 meters.
