Hydrogen Sulfide Gas Sensor

The SGX-4H2S-100 Hydrogen Sulfide sensor can detect naturally occurring gas in hot springs, natural gas, volcanic gas, and crude oil. The bacterial breakdown of biological matter can likewise produce it, handling civil wastewater and many assembling and modern cycles. Hydrogen sulfide is a dull gas with a foul smell of spoiled eggs. Contingent upon the focus, H2S gas can be harmful to people, destructive to metals, and explosive. The integrity of pipelines, infrastructure, and industrial process equipment, as well as employees' safety, all depend on the measurement of H2S levels.
