NOTE 1. Do not install the equipment in a strong convective air environment. 2. Avoid contact with organic solvents (including silicone and other adhesives), paints, chemicals, oils
and highly concentrated gases. 3. The device should not be used for a long time in the environment containing corrosive gases,
corrosive gases will damage the sensor. 4. Do not place the device for a long time in a high concentration of organic gases, long-term
placement will lead to sensor zero point drift, and slow recovery. 5. Prohibit long time storage and use in high concentration alkaline gas.
