Product Introduction
-
1. Hydrogen Sulfide Sensor (H2S Sensor) ME3-H2S Product Description
-
The ME3-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, and the H2S concentration can be determined by measuring the current.
