Product Brief

4S-H2S electrochemical hydrogen sulfide sensor

The 4S-H2S sensor is a constant potential electrolytic H2S sensor.

4S-H2S and 02 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 measuring the current.
