Product Description:
ME4-H2S Electrochemical Hydrogen Sulfide Sensor Is Used For Hydrogen Sulfide Detection In Industry And Environmental Protection
Features:
ME4-H2S type sensor is a constant potential electrolysis type H2S sensor. H2S and O2 undergo corresponding REDOX reactions at the working electrode and the opposite electrode and release charge to form current. The current is proportional to the concentration of H2S, and the concentration of H2S can be determined by testing the current.
