Description
MQ-E3-H2S is the sensor of fixed potential electrolysis type. By redox reaction, H2S and O₂release charge and form the current. The value of current is proportional to the concentration of H2S and follow the Faraday’s Law. By testing the value of current, the concentration of H2S is known.
Application
Widely used in industry, mine, or environmental protection field for detecting H2S.
