Hydrogen Sensor (H2 Sensor) ME4-H2 Product Description
-
The ME4-H2 sensor is a constant potential electrolytic H2 sensor. H2 and O2 undergo corresponding oxidation-reduction reactions on the working electrode and counter electrode, releasing charge to form a current. The magnitude of the current is proportional to the H2 concentration. By measuring the current, the H2 concentration can be determined.
