The KQT-H₂S hydrogen sulfide gas detection sensor is a constant - potential electrolysis type sensor. Hydrogen sulfide and oxygen undergo corresponding oxidation - reduction reactions on the working electrode and the counter - electrode respectively, and release charges to form an electric current. The magnitude of the generated current is proportional to the concentration of hydrogen sulfide. The concentration of hydrogen sulfide can be determined by measuring the magnitude of the current.
