Declaration:

1. 4-Series electrochemical gas sensors are designed for gas leak monitoring and alarm. They are not

suitable for long-term exposure to the gas to be measured or long-term on-line continuous detection

and analysis instruments.

2. Sensor pins must be connected through a PCB socket, Welding the pin directly will damage the

sensor.

3. Sensors should avoid contact with organic solvents, alcohol, paint, oil and high concentration of

gas, including silica gel and other adhesives.

4. Electrochemical sensors with positive output current (such as CO, H2S, SO2, NH3, etc.) require

oxygen to participate in the reaction and should be calibrated with the standard gas of air as the

background gas and test, otherwise it will destroy the sensor's performance.

5.Do not remove or insert the sensor when it is powered on. Otherwise, the sensor may be damaged

or abnormal.
