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. Note: To keep continual product development, we reserve right to change design features without prior notice.
