The GD1 sets a new standard for toxic gas detection. Using a tuneable laser diode the GD1 delivers enhanced coverage and fail safe detection.
The performance improvement marks a genuine step change for safety systems and life cycle cost savings.
The GD1 has been designed with features that provide an effective response to the detection of gas hazards in a wide range of industrial environments from offshore production facilities to wastewater treatment plants.
At the heart of the detector is a tuneable laser diode that eliminates environmental effects from sun, rain and fog.
The laser scans single absorption lines where there is no interference from other gases.
Unlike traditional methods for detecting H2S (MOS or EC cell) the GD1 needs no recalibration and can replace multiple standard detectors to cover the same risk.
The complete optomechanical design and construction is so stable that an ultra fast speed of response can be achieved while providing unparalleled service life and detector stability, thus saving on maintenance and service costs.
The detector is supplied with worldwide hazardous area approvals, is suitable for SIL2 applications and comes with a 5 year warranty.
