Line-of-sight H2S detector

23 September 2009

Groveley Detection has launched the GD1 line-of-sight Hydrogen Sulphide (H2S) detection system, which provides an effective response to the detection of gas hazards. The GD1 needs no re-calibration and can replace multiple standard detectors to cover the same risk. The open path detector incorporates Simtronics transmitter and receiver, and the demonstration was conducted by Groveley in conjunction with the Simtronics ASA.

It proved the accuracy and speed of response of the system to a variety.
The GD1 utilises a tuneable laser diode to protect over a path length of up to 100m and will instantaneously respond to the presence of any H2S gas cloud which passes between the transmitter and receiver. The laser eliminates environmental effects and scans single absorption lines where there is no interference from other gases.
The optomechanical design and construction is so stable that an ultra-fast speed of response can be achieved while providing extended service life and detector stability, which reduces maintenance and service costs.
The GD1 is also available with a dual output gas configuration. A single laser can be used to detect both methane and hydrogen sulphide, reducing cabling, installation and maintenance costs.
