Chapter 5 Calibration of Sensors
The probe is calibrated at the factory and is selectively calibrated depending on the situation on the site.
There is a need to calibrate the sensor when the following situation occurs:
1. When the measured value of the parameter is inconsistent with the known calibration standard value.
2. When dirt appears or could be seen obviously.
3. When the components are replaced.
Some system components are susceptible to time, use, and environment. To ensure the accuracy of the
instrument, it is recommended to perform routine testing under the standard conditions for the system.
5.1 Probe Settings
1. Ion electrode should not be placed in high-purity or deionized water. Otherwise, the electrolyte will get
lost, thus shortening its service life. It should not be placed for a long time.
2. When the temperature changes suddenly or severely, it will take a long time for the ion electrode to
