Choose ‘pH (2 points) 4/6/9’ (Before each operation, the electrode can be placed in the standard solution for about 60s)
After calibration of 1st point, follow with the 2nd point:
After calibration of 2nd point, follow with the 3rd point:
After above calibration, there will be the results:
Save the results and it can be queried next time.
The pH value of the buffer is measured at 25 ° C, please select the correct buffer (please refer to P30 “Buffer Table”). Before calibration, the
electrode can be activated by soaking in the solution to ensure the stability and accuracy of the calibration value and the detection value.
Onsite Calibration
If you choose pH onsite calibration, install the pH electrode in the actual water sample, and use standard portable instruments or standard
