H2S Monitoring

Hydrogen Sulfide (H2S) is a dense, colourless gas produced in industrial operations. It has an intense odour at very low levels (ppbv) and can thus be an irritant to people living near facilities (petrochemical) that produce or use this gas.  Applications for which this gas is used include rust protection of iron and steel products and calibration of environmental emissions monitoring equipment. While H2S  is useful for monitoring other gases, it is essential to also monitor its levels in facilities because H2S is a poisonous gas that is toxic to workers when inhaled. Even at levels below the toxic threshold the odour can be extremely irritating.  Hydrogen sulfide is also flammable--thus the detection of H2S sources is necessary for preventing fires.


We offer the ideal TDLAS technology for H2S monitoring. Our instruments ensure accurate and rapid response to H2S levels. The Unisearch LasIR provides:

  • Reliable, accurate data
  • Rapid response – within seconds if desired
  • Multiple location monitoring for both fire detection and combustion optimization
  • Continuous emissions monitoring
  • Freedom from interferences from other gases which could result in erroneous data
  • Easy maintenance and improved process control
