After the calibration is complete, rinse the sensor and calibration container with water and dry to ensure
the following use.
Tip: Be sure to calibrate the neutral point and then calibrate the acid point. The order cannot be reversed.
In order to ensure the accuracy of the calibration, we will provide a buffer/standard solution with
pH=9.18. After the above calibration is completed, the calibration accuracy can be verified by detecting
the pH of the buffer. The specific steps are: change the mode setting. For “on-line date”, place the Sensor
in a calibration container containing the correct amount of buffer/standard solution at pH=9.18, place the
glass bubble into the solution at least 1 cm, leave it for at least one minute, and then click on the
confirmation on the side of the mode setting. , watch online data. If the data is found to be significantly
different from 9.18, it needs to be recalibrated until there is no deviation.
You can also directly enter the value in the “Correction Parameters” box and click “factor” and
“deviation” to calibrate the factor and deviation value.
6.1.4 ORP Sensor Calibration
From the calibration menu, select the “Electrode” option to enter the electrode calibration procedure. The
interface is as shown below, and the electrode type is pre-configured, such as the box. You can then
prepare to start the calibration.
Before use, remove the protective soaking bottle or rubber sleeve with the soaking liquid on the sensor,
