6.0 Cleaning the Bluelab pH Probe

To ensure accurate readings the pH probe tip needs to be rinsed in water after

each use and cleaned prior to calibration using the following instructions.
The storage cap must always be put back on after cleaning. Always ensure it

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.
Never use RO (Reverse Osmosis), Distilled

or De-ionized 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 soil 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 3.0
After calibration, store pH probe in the

storage cap, ensuring there is enough KCl

Storage Solution to cover the probe tip.
