9.2. Calibration Procedure With pH 4.0 Solution
1) Immerse the pH probe in the calibration fluid
pH 4.0
to a minimum 3 cm (~1 inch)
depth.
2) The pH probe should be in the solution for about 4-5 minutes. During this period
gently move and rotate the probe every few seconds, keeping the pH probe
immersed in the calibration solution.
3) After about 4-5 minutes, in the application, under the “
pH ports / kHLab config
”
TAB, select the check box next to the
Calibrate pH 4
to activate this function and
click
Calibrate pH 4
4) The calibration process for the first point with
pH 4.0 solution
has been completed.
5) Remove the pH probe from the
pH 4.0
solution, and rinse it in RO water (or tap
water) for at least 2-3 minutes and dry the probe the same way as described above.
9.3. Calibration Procedure With pH 7.0 Solution
1) Immerse the pH probe in the calibration fluid
pH 7.0
to a minimum 3cm (~1in) depth.
2) The pH probe should be in the solution for about 4-5 minutes. During this period
gently move and rotate the probe every few seconds, keeping the pH probe
immersed in the calibration solution.
3) After about 4-5 minutes, in the application, under the “
pH ports / kHLab config
”
TAB, click
Calibrate pH 7
4) The calibration process for the second point with
pH 7.0
solution has been
completed.
5) Remove the pH probe from the
pH 7.0
solution, and rinse it in RO water (or top
water) for at least 2-3 minutes and dry the probe the same way as described above.
In the case when obtained Alkalinity values are not as expected (e.g. confirmed by a
precise laboratory test), make sure that the pH probe is properly calibrated by running the
calibration procedure again.
