4S-H2S electrochemical hydrogen sulfide sensor
Product details
product details
The 4S-H2S sensor is a constant potential electrolytic H2S sensor. H2S and O2 undergo corresponding oxidation-reduction reactions at the working electrode and counter electrode, releasing charges to form a current. The magnitude of the current is proportional to the concentration of H2S, and the concentration of H2S can be determined by testing the magnitude of the current.
Sensor characteristics
Low power consumption, high precision, high sensitivity, wide linear range, strong anti-interference ability, excellent repeatability and stability.
Main applications
Widely suitable for detecting hydrogen sulfide in industry, underground mining, and environmental protection.
