H2S Gas Sensors

H2S Gas Sensors and Accessories – General Monitors

General Monitorsʼ H2S Gas Sensors are solid state devices, designed and manufactured for long life and fast response.

They are selective to H2S and remain unaffected by high concentrations of other substances like hydrogen, sulfur dioxide, and gasoline vapors, which are often present in facilities that process sour gas and crude oil. A high tolerance to a broad range of temperatures and humidity enable these sensors to operate in rugged environments, as does their capacity to withstand exposure to high H2S concentrations over short periods.


  • Solid-state operation functions in the harshest environments
  • Highly selective — does not respond to hydrocarbons — for low risk of false alarms
  • Unaffected by over-range exposure reduces need for sensor replacement
  • Robust mechanical design
  • Resistant to high humidity and wide range of ambient temperatures
  • Specific sensors meet ISA-92.0.01 performance standard


  • Refineries
  • Drilling rigs and platforms
  • Gas collection and distribution facilities
  • Gas gathering facilities
  • Mud-logging operations
  • Sulfur recovery / de-sulfurization facilities
  • Chemical plants
  • Wastewater treatment facilities
