26.0 Cleaning the Bluelab pH Probe
To ensure accurate readings the pH probe tip needs to be rinsed in water and cleaned
prior to calibration using the following instructions. After cleaning, use the probe
straight away, or place the storage cap on the probe tip. Always ensure the cap
contains enough Bluelab pH Probe KCl Storage Solution to cover the probe tip.
Remove storage cap from pH probe.
Hold the top of the storage cap, twist the cap to
loosen then remove.
Rinse pH probe tip under fresh tap water.
Fill a small plastic container with clean tap
water. Add a small amount of Bluelab pH Probe
Cleaner or mild detergent (dishwashing liquid).
Gently stir the probe tip in the mixture.
Ensure that you do not ‘knock’ the pH 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.
If the probe tip requires removal of heavy
contamination: Gently brush around the
glassware with a few drops of Bluelab pH Probe
Cleaner or mild detergent (dishwashing liquid)
and a soft toothbrush.
Rinse well under fresh running tap water to
remove all traces of the detergent mixture.
Calibrate pH probe after cleaning, see section
14.0. After calibration use straight away or
store pH probe in the storage cap, ensuring KCl
Storage Solution covers the probe tip.

25.0 Hydrating the pH probe
Hydrate the pH probe in Bluelab pH Probe KCl Storage Solution when:
• the probe tip has not always been stored in KCl storage solution, to improve the
reading response speed.
• the probe tip has been accidentally allowed to dry out.
Never store the pH probe in RO (Reverse Osmosis), De-ionized or Distilled water. Pure water changes the chemistry
in the reference, causing the probe to die.
Clean the pH probe tip. Ensure the probe tip is cleaned
before hydrating. See section 26.0 for instructions.
Add enough Bluelab pH Probe KCl Storage Solution to a
plastic container to submerge the pH probe tip.
Loosen, then remove the storage cap (if required). Place
the pH probe upright in a the KCl solution.
Leave to soak for up to 24 hours. After hydration, always
calibrate the pH probe to ensure accuracy, see section 14.0.
