Precautions for the use of electrochemical sensors

The first but most important thing is to use it within the allowable specifications.

When it comes to measuring gas sensitivity, please make sure to conduct the test in clean air and avoid blowing the measured gas directly from the front. Blowing the measured gas strongly directly onto the sensor's air inlet surface will result in a high sensitivity reading for the sensor in this state. Additionally, the sensor's air inlet surface should not be blocked or contaminated—blocked air holes are one of the causes of low sensitivity. After prolonged use in a high-concentration gas environment, the sensor may recover to its initial state slowly. Keep the sensor away from organic solvents, paints, chemicals, oils, and high-concentration gases. The working electrode and reference electrode should be short-circuited during sensor storage. The sensor must be aged for at least 24 hours before use, and tin soldering is prohibited during installation.

There are some things you should not do if you want to measure gas sensitivity successfully:

• Do not break or bend the sensor pins, or subject the sensor to excessive impact or vibration.
• Do not use the sensor if the housing is damaged or if there are other defects.
• Do not disassemble the sensor arbitrarily, as electrolyte leakage may cause harm.
