Contact SupplierThe Online H₂S (Hydrogen Sulfide) Gas Leak Detector is designed for continuous, real-time monitoring of H₂S gas concentrations in hazardous and industrial environments. Hydrogen sulfide is a toxic and flammable gas, often found in oil refineries, wastewater treatment plants, and chemical processing units. This detector helps protect personnel and equipment by providing early warnings of gas leaks.
