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 an oxygen-free environment, otherwise, it will damage the function of the 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 to bend and breaking pins；
• 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 the reference electrode of the sensor shall be in a short circuit when stored.；
