3.0 Probe Maintenance

Your Bluelab OnePen™ Replacement Probe needs to be cleaned, kept hydrated, and
pH calibrated regularly to extend its life and continue to provide accurate
measurements.
3.1 How to hydrate your Bluelab OnePen™ probe
Hydration is essential for accurate pH readings.
Without proper hydration, your readings may drift, and the probe may break.
To ensure the probe glass bulb and porous wick are properly maintained, hydrate the
Bluelab OnePen™ glass bulb in Bluelab Probe KCl solution.
Bluelab OnePen™ hydration
To hydrate your OnePen™, follow the steps below.
1. Make sure the glass bulb is clean and free from contamination. See section
3.2 for cleaning instructions
2. Place a few drops of KCl Storage Solution on the sponge in the storage cap.
3. Leave to soak for 24 hours.
4. After hydration, rise the probe tip in fresh water, then follow the instructions
to calibrate.
IMPORTANT: Never use RO (reverse osmosis), deionised, or distilled water, as these
can permanently damage the probe.
IMPORTANT: Do not soak the titanium electrodes in KCl solution for any length of
time.
IMPORTANT: Never let your pH bulb dry out. If you accidently let it dry read
