9.0 Cleaning
To ensure accurate readings the probe tip needs to be kept clean at all times.
Cleaning prior to calibration is necessary for successful calibration.
Remove storage cap/dibber.
Rinse probe tip under fresh tap water.
Fill small plastic container with clean 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 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 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 water to remove all
traces of the detergent mixture.
Calibration of the probe is required after every clean.
See the pH calibration in section 11.0. Place storage
cap/dibber back onto the probe tip.
