3. Wait until the conductivity reading stabilises.
The conductivity reading should be within
1 CF, 0.1 EC, 50 TDS or 70 ppm of the values in
the table above.
If the reading is lower than 2.77 EC;
1. Ensure that the 2.77 EC standard solution is
fresh and uncontaminated and of a qualified
brand; if you are unsure, use new solution.
NEVER add water to solutions.
2. Wait 1 – 2 minutes for the probe to reach the
solution temperature. In extreme
temperatures 5 – 10 minutes may be
necessary.
NOTE: Probes that read low generally only require
cleaning.
3. If the reading remains higher than 2.9 EC after
testing all of the above, check solution has not
evaporated during storage.
Cleaning the pH Probe
To ensure accurate pH readings Bluelab recommend
that the pH Probe is rinsed in clean fresh water
before replacing the wetting cap and that it is
cleaned when required by following the instructions
below;
1. Rinse pH probe tip under fresh water.
2. Fill a small container with clean water and add
a small amount of mild detergent
(dishwashing liquid).
3. Gently stir the pH probe tip in the mixture.
Ensure that you do not ’knock’ the probe on
the side of the container as this may cause
damage to the probe. Rinse well under fresh
running water to remove all traces of the
detergent mixture.
4. ONLY if the probe tip requires removal of
heavy contamination, gently brush around the
glassware with a few drops of mild detergent
(dishwashing liquid) and a soft toothbrush.
DO NOT pull out or touch the wick.
5. Rinse well under fresh running water to
remove all traces of the detergent mixture.
6. Recalibrate the pH probe. See the pH
calibration section on page 8 or place wetting
cap back onto probe tip.
