Precautions
The probe contains sensitive optical and electronic components. Ensure that the probe is not subject to severe mechanical impact. Damage to the sensor due to impact or manpower will not be covered by the warranty. Water ingress to the sensor due to replacement of the pH electrode is not covered by the warranty.
Maintenance schedule and method
Maintenance schedule
It is recommended to periodically calibrate or clean the sensor surface according to the actual application scenario.
| Maintenance tasks, | Recommended maintenance frequency |
| Calibrate the sensor (if required by the competent authority) | According to the maintenance schedule required by the competent authority |
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.
