Maintenance method
Sensor maintenance
1) External surface of the sensor: Wash the external surface of the sensor with tap water. If debris remains, wipe it with a moist soft cloth.
2) Check the cable of the sensor: The cable should not be tight during normal work, otherwise the internal wires of the cable will be easily broken and the sensor will not work properly.
3) Sensor storage: When the sensor is not in use, you should fasten the black plastic cap and check whether the sponge inside is wet. If it is not wet enough, please add 3mol / L potassium chloride solution and let the electrode be stored in the solution with potassium chloride.
