Hydrogen Sulfide Analyzer Module
Hydrogen sulfide (H2S) is a strong smelling compound often associated with industrial processes, such as sewage treatment or waste disposal.
H2S is not listed among the six criteria health pollutants cited by the U.S. EPA. However, legislation controlling the levels of H2S in ambient air is defined in most countries and many jurisdictions have ambient exposure standards for H2S.
