6.Precautions for use

1. As shown in the figure, the sensor 2 and 5 are heating electrodes, and 1, 3 or 4, 6 are measuring electrodes. If the voltage is applied to 1, 3 or 4, 6, the measuring electrode will burn out. If it is applied to 2 and 4, no signal will be obtained.

2. Do not apply high voltage, which will cause the sensor to be damaged or the performance to change.

3. Avoid long-term exposure to volatile silicon compound vapors, such as hair spray, silicone adhesive, and putty, which will cause the sensitive materials to be covered and the product to fail.

4. The sensor is prohibited from contacting water or liquid, which will cause the sensitive material to fall off, causing the sensor performance to change or fail.

5. Avoid using it in a highly corrosive environment, such as using it in an environment containing hydrochloric acid, nitric acid, strong alkaline substances or alkali metal salts, which will cause the sensitive material to deteriorate, the electrode to be corroded, and the sensor to be damaged.

6. Avoid using it in extreme environments, such as long-term use in high-concentration gas, high humidity, high temperature, and high-pollution environments, which will cause the performance of the sensor to change.

7. Avoid strong vibration and impact, such as vibration during transportation and falling from a height, which may cause the sensor electrode to break or be damaged.

8. It is recommended to solder the sensor manually. Try to avoid using reflow soldering without sufficient testing and reasonable technical guidance.

    When welding, try to use manual welding, welding temperature ≤ 250 degrees, welding time less than 3 seconds, equipment welding, such as wave soldering, use flux with less chlorine content, speed 1-2 meters/minute, temperature 250±10 degrees, one-time welding, if conditions permit, apply film to the sensor mesh cap to avoid strong odor changing the sensor performance.
