Key Product Features

  • Easy to use
  • Rugged and robust instrument case
  • External semi-conductor probe for fast detection of leaks

The GMI First Responder is a combustible gas indicator designed for emergency response technicians in the gas industry.

The First Responder detects flammable gas at ppm, LEL and % Vol. levels, with the addition of carbon monoxide for internal atmosphere monitoring.

An optional external range diffusion probe with high speed semi-conductor sensor enables rapid response in detecting small fitting leaks.

  • ppm, LEL and Volume flammable gas ranges for leak detection and general safety monitoring
  • Carbon monoxide range for internal atmosphere monitoring
  • Probe mounted semi-conductor sensor (range 0-10,000 ppm), providing instant response leak detection with audible/visual ‘Ticker’ (Geiger) alarm indication
  • Simple four-button operation allowing access to all features
  • Automatic and manual datalogging
  • Integral pump with pressure sensor for flow fail detection, with sample path protected by hydrophobic filter
  • Comprehensive range of probes and accessories available
  • Rugged polypropylene case, sealed to IP54 rating
  • Re-chargeable or alkaline battery options
  • Fully certified to international standards
