24.0 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 13.0. After calibration use straight
away or store pH probe in the storage cap,
ensuring there is enough KCl Storage Solution
to cover the probe tip.
