Product Description

The controlled potential electrolysis principle is applied on the H2S sensor. Three electrodes installed in the electrolytic cell, which are working electrode, grounding electrode and comparison electrode. A polarizing voltage is applied at the same time. The electrolytic cell is isolated from outer part by a membrane. the sample gas passes through it and reaches to working electrode,  produce an oxidation-reduction. A small current will output from the sensor. This current is proportional to the H2S gas Concentration.
