Interference Resistance Low interference from common gases, sensitive to high concentrations of Cl2, SO2, etc. Avoid contact with strong oxidizing gases Working principle
Using an electrochemical three-electrode system, the H2S gas diffuses into the sensor. After that, an oxidation reaction occurs at the working electrode, generating electron transfer and forming an electric current. The magnitude of the current is proportional to the concentration of H2S. The auxiliary electrode stabilizes the potential, and the reference electrode provides a reference potential. Through circuit amplification, it is converted into a readable ppm signal, enabling precise monitoring.
