ME2- O3- 16x15 O3 gas sensor
ME2-O3-16x15 electrochemical gas sensor is fuel cell type, which utilizes the electrochemical oxidation process
of O3 gas on the working electrode. The current produced in electrochemical reaction of the target gas are in
direct proportion with its concentration while following Faraday law, then concentration of the gas could be get
by measuring value of current.

8. Application Notes:
Do not break and bend the PCB terminals;
To preheat for no less than 48hs before using;
Do not take apart the sensor, otherwise electrolyte leakage can cause sensor damage;
Sensor shall avoid organic solvent, coatings, medicine, oil and high concentration gases；
All 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 ME sensors shall not be applied in corrosive gas environment, or the sensor will be damaged；
Please test the zero point of gas sensors in clean atmosphere；

Sensors shall be avoided to face the gas, which flow directly from front side；
Blowhole of the sensor should not be blocked and polluted, which will cause the sensitivity decrease;
Do not open and damage the above waterproof breathable membrane of the sensor;
Excessive impact or vibration should be avoided；
Do not use the sensor when the shell is damaged；
It takes some time for the sensor to return to normal state after applied in high concentration gas；
Working electrode and reference electrode of the sensor shall be in short circuit when stored；
Please do not encapsulate the sensor using melt adhesive and sealant, whose curing temperature is higher
than 80°C;
Please do not expose and use the sensor in high concentration alkaline gas for a long time.
Note: To keep continual product development, we reserve right to change design features without prior notice！
