## **8.Application Notes:** 

- Sensor shall Avoid organic solvent, coatings, medicine, oil and high concentration gases ； 

- All ME 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 sensitivity of gas sensors in clean atmosphere ； 

- Sensors Shall be avoided to face the gas, which flow directly from front side ； 

- To avoid to bend and break of pins ； 

- Blowhole of the sensor should not be blocked and polluted, which will cause the sensitivity decrease; 

- 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 ； 

- Do not take apart the sensor, otherwise electrolyte leakage can cause sensor damage; 

- Working electrode and reference electrode of the sensor shall be in short circuit when stored. ； 

- To preheat over 48hs before using and soldering forbidden;
