Teledyne GD10P Infrared Gas Detector For Methane (CH4) - 100% LEL (4.4% Vol.)

Description

The GD10P series of infrared gas detectors has set the standard in the areas of performance, safety, response time, stability and maintenance.

The GD10P differs from all other infrared gas detectors because it uses a silicon-based solid-state infrared source instead of a filament. The patented Sim-SourceTM solid state IR light source is extremely stable. The intensity of the IR light does not deteriorate over time like a filament, therefore the GD10P never requires calibration for compensation of this signal. In addition to the stability, the Sim-SourceTM light has the best longevity in the industry and is covered by a15-year full replacement warranty.

All optical components are mounted on single metal platform which provides stability of measurements even in high vibration environments. The dual path-length design compensates for temperature, humidity, and particulates in the environment. The heated optics eliminate the adverse effects of moisture in high humidity applications. There are also two user-adjustable levels of dirty optics indications, a warning and an alarm. The GD10P is so robust that it will operate and alarm with up to 70% optics signal blockage. Optics can be easily cleaned with a moist cloth and there is no need to declassify the area for this service procedure.

The GD10P also excels with the ultra-fast response times, responding to gas exposures in only a few seconds. The patented dual layer weather shield design allows gas to rapidly enter and exit the measurement chamber. Since the weather shield contains no sinters or mechanical filters, it provides the same fast response under any conditions: from stormy offshore platforms to wind-swept desert applications. Response times can be adjusted through a HART hand-held.
