Principle Introduction:
Winsen Electronics, produces sulphur dioxide/SO2 gas sensor, by measuring current based on the electrochemical principle, for industrial use.
ME4-Cl2 chlorine gas sensor is constant potential electrolysis type. Oxidation-reduction reaction with chlorine gas and oxygen take place respectively on the working electrode and on the counter electrode. The process releases electric charge and generates current. The current is in direct proportion to the concentration of chlorine gas and conform to faraday's law. So the concentration of the target gas could be got by measuring the value of current.

It is used for chlorine gas detection in the occasions such as chemical engineering, medicine and environmental protection field.
