UGT-E4-H2S Hydrogen Sulfide Gas Sensor

UGT-E4-H2S Hydrogen Sulfide Gas Sensor

product overview

The UGT-E4-H2S hydrogen sulfide gas detection sensor is a constant potential electrolytic sensor. Hydrogen sulfide and oxygen undergo corresponding oxidation-reduction reactions on the working electrode and the counter electrode, respectively, and release charges to form a current. The magnitude of the generated current is proportional to the concentration of hydrogen sulfide. By testing the magnitude of the current, the concentration of hydrogen sulfide can be determined.
