Detection of Hydrogen Sulphide
Who would not know the smell of rotten eggs or stink bombs? The evil smell of hydrogen sulphide (H2S) is detected by the human nose even in very small concentrations. As little as 20 ppb will be detected by an average human nose. Why then buy a gas detector for hydrogen sulphide?
Hydrogen sulphide is no longer observable starting with 100 to 150 ppm. This exactly the concentration at which this gas starts causing serious symptoms. 300 ppm will cause irreversible health damage, 1.000 ppm are lethal.
Hydrogen Sulphide in the Environment
Hydrogen sulphide is produced at any process of biological degradation of organic material. Consequently this gas is present wherever waste water, solid waste or fecal matter is present. Entering channels, pits, tunnels, deposits or biogas plants without a hydrogen sulphide gas detector would be extremely dangerous.
The largest source of hydrogen sulphide by far is crude oil. Therefore Petrochemical and chemical plants are the largest users of hydrogen sulphide gas detectors.
People working in an ambience with potential presence of hydrogen sulphide must use hydrogen sulphide gas detectors as personal protection! Plants must be monitored for leaks by fixed gas detectors. Compur Monitors offers a wide range of professional hydrogen sulphide gas detectors: Monitox, Statox 501, Statox 505, Statox 502, Statox 560, Micro 5, Microclip and Tracer. The most advanced hydrogen sulphide gas detector is surely the Statox 560 with self – test.
