Precautions
- Disable soldering during installation.
- Pins must not be broken or bent.
- Electrolyte leakage will cause damage; do not disassemble the sensor at will.
- Avoid contact with organic solvents (including silicone and other adhesives), paints, chemicals, fuel oils, and high-concentration gases.
- Electrochemical sensors must not be fully encapsulated with resin materials or placed in an oxygen-free environment; otherwise sensor performance will be damaged.
- Electrochemical sensors should not be used in environments containing corrosive gases, as these can damage the sensor.
- Avoid direct vertical intake when testing and applying the sensor.
- The air intake surface must not be blocked or contaminated.
- The waterproof and breathable membrane above the sensor must not be opened or damaged.
- The sensor must not be subjected to excessive impact or vibration.
- Do not use the device if it is damaged or deformed.
- In high-concentration gas environments, the return to the initial state may be slow after long-term exposure.
- During storage, the working electrode and reference electrode should remain in an open state.
- Do not encapsulate the sensor with hot-melt adhesives or sealants with curing temperatures above 80°C.
- Avoid long-term storage and use in environments with high-concentration acidic gases.
