Point IR Gas Detector – GD10P



The Simrad GD10P gas detector is the benchmark for combustible gas detection on offshore installations to detect Hydrocarbons or CO2 gases. It has set the standard for gas detectors in the areas of safety, stability and low maintenance. GD10P comes with 5 years warranty.


  • Life-time Stability
    The SimSource infrared light source is a solid-state component with a stable output and 60 years of expected lifetime. This, together with the Simtronics IR-path design gives you a detector with unparalleled stability.
  • No False Alarms
    Unlike most gas detectors in use today, the GD10P will give an error signal and not cause gas alarms in case of detector failure.
  • No Poisoning or Saturation
    Immune to silicon vapors, H2S and other widely used agents.
    High gas concentrations will not saturate the detector.
    Can be used to detect gases where oxygen is not present, e.g. in sub-sea production units


  • Offshore Platforms
