ME3-H2S Hydrogen Sulphide Sensor Constant Potential Electrolytic Type 500ppm

Product Description
ME3-H2S Hydrogen Sulfide Sensor Constant Potential Electrolytic Type



ME3-H2S sensor is a constant potential electrolytic H2S sensor. H2S and O2 undergo corresponding redox reactions at the working electrode and counter electrode and release charges to form a current. The current is proportional to the H2S concentration. The H2S concentration can be determined by testing the current.



Main application
It is widely suitable for the detection of hydrogen sulfide in industry, mine and environmental protection.
