The OMA H2S Analyser monitors the UV-Vis absorbance in a continuously drawn liquid/gas sample and outputs real-time hydrogen sulfide concentration.

Please contact us directly to purchase this item

The OMA H2S analyser  continuously measures H2S concentration using a full-spectrum UV-Vis spectrophotometer, harvesting the power of collateral data to establish excellent dynamic range and sustain accuracy in the presence of cross-interfering species. With an ultra-safe fiber optic design and solid state build, this system is simple to install and relentlessly reliable.


  • Continuously measures H2S concentrations in a liquid or gas process stream
  • Up to 4 additional software benches for additional analytes (e.g. SO2 , R-SH)
  • Totally solid state build with no moving parts - modern design for low maintenance
  • Ultra-safe fiber optic design with dedicated sample flow cell - no toxic/corrosive sample fluid in analyser enclosure
  • Decades of field-proven performance in the world's harshest industrial environments
