The Simtronics GD1 by Teledyne detects H2S gas hazards, making it suitable for use in multiple industries, including offshore production facilities and wastewater treatment plants.

At the heart of the detector is a tunable laser diode that eliminates environmental effects from the sun, rain, sand, 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 are stable, resulting in ultra-fast response time 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 SIL 2 applications, and comes with a five-year warranty.
