ME4-SO2-E4 SO2 Gas Sensor 0 - 100ppm Constant Potential Electrolytic Type

Product Description
ME4-SO2-E4 Sulfur Dioxide Sensor Constant Potential Electrolytic Type



ME4-SO2-E4 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. The fourth electrode of the sensor, the auxiliary electrode, is used to compensate the zero-point current, so that it has the characteristics of strong signal level and low zero-point current.



Main application
It is widely used in urban atmospheric environment monitoring, enterprise environmental monitoring, unorganized emission pollution gas monitoring in factories, emergency monitoring and environmental assessment monitoring.
