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.

Before using, power on to aging for more than hours is necessary. Pins can t be broke off or bent. Don t disassemble the sensor to avoid the damage caused by electrolyte leakage. Avoid contacting organic solvent (including Silicone rubber and other adhesive coatings, medicine, oil and high concentration gases. All the electrochemical sensors shall not be encapsulated completely by resin materials, and shall not immerse in pure oxygen environment, otherwise, it will damage the function of sensor All electrochemical sensors shall not be applied in corrosive gas environment, or the sensor will be damaged Zero calibration should be finished in clean air. During test and usage, sensors should avoid the gas inflow vertically The side for inflow can t be choked and polluted. The laminating film above the sensor surface can t be uncovered and damage. Excessive impact or vibration should be avoided It takes some time for the sensor to return to normal state after it is applied in high
