10.0 Storing the Bluelab Combo Meter
Store the Combo Meter in a cool, dry and clean place when not in use.
Keep out of direct sunlight.
Keep Combo Meter out of direct sunlight to prevent irreparable damage to the LCD
reading display.
The Combo Meter is not waterproof but will withstand occasional water splashes.
If the Combo Meter is splashed, wipe dry as soon as possible.
Remove batteries if the Combo Meter is to be stored for a prolonged period.
Remove pH probe if storing the Combo Meter without use for longer than two to
three weeks and check regularly that the pH probe tip has not dried out.
When storing the pH probe, the pH probe tip must be kept moist.
To prepare the pH probe for storage, add enough Bluelab pH Probe KCl Storage
Solution to the storage cap so the probe tip is covered. Then replace the cap and
store in a secure place. DO NOT use RO (Reverse Osmosis), Distilled or De-ionized
water. Pure water changes the chemistry in the reference, causing the probe to die.

9.0 Hydrating the pH probe
Hydrate the pH probe in Bluelab pH Probe KCl Storage Solution when:
• the probe tip has not always been stored in KCl storage solution, to improve
the reading response speed.
• the probe tip has been accidentally allowed to dry out
Never use RO (Reverse Osmosis), De-ionized or Distilled water.
Pure water changes the chemistry in the reference, causing the probe to die.
Loosen, then remove the storage cap.
Place the pH probe upright in a plastic
container.
Clean the pH probe tip.
Ensure the probe tip is cleaned before
hydrating. See section 8.0 for instructions.
Add enough Bluelab pH Probe KCl
Storage Solution to a plastic container to
submerge the pH probe tip.
Leave to soak for at least 24 hours.
After hydration, always calibrate the pH
probe to ensure accuracy, see section 3.0.
