GS+7H2S Hydrogen Sulfide (H2S) Sensor For Industrial Safety Industrial General
Working Principle:
The GS+7H2S sensor operates based on the electrochemical three - electrode principle. Hydrogen sulfide gas diffuses through a permeable membrane and reacts with chemicals at the working electrode, while oxygen reacts at the counter - electrode. These reactions release charges to form a current, and the magnitude of the current is proportional to the hydrogen sulfide concentration. By measuring the current, the concentration of hydrogen sulfide can be determined.
