Product Description:

ME4-H2S hydrogen sulfide gas sensor is constant potential electrolysis type. Oxidation-reduction reaction with hydrogen sulfide and oxygen take place respectively on the working electrode and on the counter electrode. The process releases electric charge and generates current. The current is in direct proportion to the concentration of hydrogen sulfide. So the concentration of the target gas could be got by measuring the value of current.
