  • Description


GD10P – CO2 Infrared Gas detector

Our ultimate Infra-Red point detector with filter wavelenghts for CO2 detection. GD10P may be stand-alone duct mounted, or used in sampling systems.

Life-time stability

The SimSource infrared light source is a solid-state component with a stable output and 60years of expected lifteime. This, together with the Simrad Optronics 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
Low maintenance costs

GD10P requires no regular field maintenance, apart from cleaning the optics. It has a fixed factory calibration, and is not recalibrated during its lifetime.
