5.2 pH probe cleaning
Over time, nutrient salts build up on the glassware of the
pH probe when it is in the sample pot. This can effect pH
readings so cleaning once a month is important. ALWAYS
CLEAN PRIOR TO CALIBRATING
1. Rinse pH probe tip under fresh water.
2. Fill a small container with clean water and add a small
amount of Bluelab pH probe cleaner or 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 detergent mixture.
4. Only if the probe tip requires removal of sediment, gently
brush around the glassware with a few drops of Bluelab pH
probe cleaner or 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. Calibrate probe. See pH calibration on page 25
