The 4S-SO2 sensor is a constant potential electrolytic gas sensor. SO2 gas and O2 undergo corresponding oxidation-reduction reactions at the working electrode and counter electrode, releasing charges to form a current. The magnitude of the current is proportional to the gas concentration, and the gas concentration can be determined by testing the current magnitude.
Low power consumption, high precision, high sensitivity, wide linear range, strong anti-interference ability, excellent repeatability and stability.
Widely suitable for the detection of SO2 gas in the industrial field.
