GasLab offers hydrogen sulfide sensors and other gas sensors used in commercial applications.
Hydrogen sulfide (H2S) is a colorless, poisonous, corrosive and flammable gas. It is produced naturally from the microbial breakdown of organic matter such as in sewers, and is often associated with the smell of "rotten eggs." Although the odor of hydrogen sulfide gas can be detected in as small as 0.00047ppm, OSHA limits exposure to 10ppm over an 8-hour workday. At concentrations above 800ppm H2S is dangerous to humans.
Dual-Gas Sensors combine commonly measured gases like carbon monoxide and hydrogen sulfide into a single industry-standard footprint to reduce costs in hand-held gas detectors.
Note that electrochemical sensors must be stored in sealed containers between 37° and 68°F (3° and 20°C) for long life. Some suppliers do not do this. Our sensors are stored in sealed containers in a refrigerator at 40°F (4.4°C) to provide the longest sensor lifespan when it is delivered to you.
