Product Introduction
1. Hydrogen Sensor (H2 Sensor)ME3-H2 Product Description
The ME3-H2 electrochemical gas sensor operates on the electrochemical principle, where the target gas undergoes oxidation-reduction reactions on the working and counter electrodes, releasing charge and generating a current through the external circuit. The current is proportional to the gas concentration, enabling quantitative measurement of the target gas.
