4S-CL2 Electrochemical Chlorine Gas Sensor
4S-CL2 Electrochemical Chlorine Gas Sensor
Product details
product details
The 4S-CL2 sensor is a constant potential electrolytic chlorine gas sensor. CL2 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 chlorine gas 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 the detection of chlorine gas in industrial applications.
