4C2H5OH-100 4-Series Electrochemical Gas Sensor Gas Leak Monitoring And Alarm
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.
