Precautions for use of electrochemical sensor

　　Please use within the scope of the specification;

　　Gas sensitivity measurement, please in a clean atmosphere;

　　Direct the measured gas to the sensor ventilation surface strong blow, in this state the sensor to the sensitivity of the gas will be very high;

　　Gas sensitivity measurement, should avoid the determination of gas blowing from the front;

　　Sensor pin is forbidden to break and bend;

　　The sensor ventilation surface should not be blocked, should not be polluted, stomatal blockage is one of the reasons leading to low sensitivity;

　　Non-excessive impact or vibration sensors;

　　Do not use when the sensor shell is damaged or other damaged conditions;

　　After the sensor is used in high concentration gas environment for a long time, the recovery to the initial state is slow.

　　Sensor to avoid contact with organic solvents, coatings, pharmaceutical, oil and high concentration gas;

　　Electrolyte leakage will cause damage, please do not disassemble the sensor;

　　The working electrode and the reference electrode should be in short circuit when the sensor is stored.

　　It must be aged no less than 24 hours before use. Solder welding is prohibited during installation.
