  • Description


Our ultimate Infra-Red point detector with versions covering a wide range of combustible gases.

Life-time stability

The SimSource infrared light source is a solid-state component with a stable output and 60 years of expected lifteime. This, together with the Simtronics IR-path design gives you a detector with unparallelled 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 poisioning or saturation
  • Immune to silicon vapours, 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
