8.0 Cleaning the Bluelab Soil pH Probe
To ensure accurate readings the soil 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 soil pH probe.
Hold the top of the storage cap, twist the cap to
loosen then remove.
Rinse soil 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 soil pH probe after cleaning, see
section 3.0 After calibration, store soil pH probe
in the storage cap, ensuring there is enough KCl
Storage Solution to cover the probe tip.
