Put the electrode in pH 6.86 or 7.00 buffer solution and
wait until the value is stable, calibrate the first point .
Then take the electrode out of the buffer solution, rinse
and dry it with a paper towel.
Put the electrode in pH 4.01 or 9.18 buffer solution and
wait until the value is stable, calibrate the second
point .Then take the electrode out of the buffer solution
rinse and dry it with a paper towel.
Electrode Installation
It is recommended pH electrode to be installed in the flow cell for more stable and
accurate measurement.
If electrode is installed in the pipe, the right angle should be 15°~165°.
