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.
