Hydrogen sulfide (or Hydrogen Sulphide) is the chemical compound with the formula H2S. This colorless, toxic and flammable gas is partially responsible for the foul odor of rotten eggs and flatulence

It often results from the bacterial break down of sulfites in nonorganic matter in the absence of oxygen, such as in swamps and sewers (anaerobic digestion). It also occurs in volcanic gases, natural gas and some well waters. The odor of H2S is commonly misattributed to elemental sulfur, which is in fact odorless.

Hydrogen sulfide is considered a broad-spectrum poison, meaning that it can poison several different systems in the body, although the nervous system is most affected.

For detection of hydrogen sulfide (or Hydrogen Sulphide), a portable or fixed gas detector can be used. Most portable H2S detectors are suitable for work in hazardous areas. We also offer a wide variety of fixed H2S detectors. Contact Airmet for more options.
