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 be immersed in an oxygen-free environment, otherwise, it will damage the function of a sensor；
- All ME sensors shall not be applied in a corrosive gas environment, or the sensor will be damaged；
- Please test the sensitivity of gas sensors in a clean atmosphere；
- Sensors Shall be avoided to face the gas, which flows directly from the front side；
- To avoid bending and breaking pins；
- The Blowhole of the sensor should not be blocked and polluted, which will cause the sensitivity to 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 its normal state After being applied to high-concentration gas；
- Do not take apart the sensor, otherwise, electrolyte leakage can cause sensor damage;
- The working electrode and reference electrode of the sensor shall be in a short circuit when stored.；
- To preheat over 48hs before using and soldering forbidden;
- Note: To keep continual product development, we reserve the right to change design features without prior notice
