1. Hydrogen Sulfide Sensor (H2S Sensor) ME4-H2S Product Description
-
The ME4-H2S sensor is a constant potential electrolytic H2S sensor. H2S and O2 undergo corresponding oxidation-reduction reactions at the working electrode and counter electrode, releasing charge to form a current. The current magnitude is proportional to the H2S concentration. By measuring the current, the H2S concentration can be determined.
