Product Introduction
1. Sulfur Dioxide Sensor (SO2 Sensor) ME3-SO2 Product Description
The ME3-SO2 electrochemical gas sensor is based on the electrochemical principle, using the measured gas to undergo corresponding oxidation-reduction reactions on the sensor's working electrode and counter electrode, releasing charge, and forming a current through the external circuit. The current magnitude is proportional to the gas concentration, thereby achieving quantitative measurement of the target gas.
