The FS4EC/H2S industrial electrochemical hydrogen sulfide sensor is designed based on the three-electrode electrochemical principle. It detects gas by the reduction reaction occurring at the working and counter electrodes, releasing charges to form a current. The magnitude of the current is proportional to the gas concentration according to Faraday’s law, allowing determination of gas concentration by measuring the current.
