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.
