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 tunable 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.

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.

Supplied with worldwide hazardous area approvals. Suitable for use in systems with SIL2 requirement.

No calibration required throughout its entire life

No cross interference with other gases

Maximum sensitivity

The laser diodes that are used are specially designed for complete selectivity, maximum sensitivity, and total reliability.

This laser technology makes GD1 immune to external disturbances such as sunlight, rain or fog. The wavelength of the laser diode is monitored more than 500 times per second to ensure that the absorption ray perfectly matches the gas to be detected, and to eliminate any on-site calibration operations. Made entirely of stainless steel and equipped with heated optics, the GD1 is ideal for monitoring structures outdoors, along fences , at the boundaries of property, and more.
