Maintenance schedule

It is recommended to periodically calibrate or clean the sensor surface according to the actual application scenario. The calibration sequence for the three-point calibration is that the first point calibration is at pH 4.0, the second point calibration is at pH 6.86, and the third point calibration is at pH 9.18 in a buffer solution. Refer to the MODBUS document for specific calibration methods.


Maintenance tasks, Recommended maintenance frequency
Calibrate the sensor (if required by the competent authority) According to the maintenance schedule required by the competent authority

Sensor maintenance

  • 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.
  • 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.
  • 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.
