ME4-SO2 Sulphur Dioxide Gas Sensor 200ppm Constant Potential Electrolytic Type

Product Description
ME4-SO2 Sulfur Dioxide Sensor Constant Potential Electrolytic Type



ME4-SO2 sensor is a constant potential electrolytic SO2 sensor. SO2 and O2 undergo corresponding redox reactions at the working electrode and the counter electrode and release charges to form a current. The current is proportional to the SO2 concentration. The SO2 concentration can be determined by testing the current.
