(3) Cleaning
Be sure to wash the pH electrode after each pH calibration or measurement with water (distilled, pure or tap
water). If left unwashed, the liquid measured tends to form a film on the surface of the electrode, causing
measurement errors. Always wash the pH electrode every time after use.
(4)
Usable life
The pH electrode is a consumable. Its useful life varies depending on the liquid to be measured, pH value or
temperature.
(5) Deposit of white potassium chloride crystals
A deposit of white crystals is sometimes found on the tip of the electrode or protection bottle; this does not
pose a problem when using the instrument. The deposit is easily washed off with tap water.
If it does not come off with tap water, soak the electrode in warm water to remove it.
Do not lick or swallow the potassium chloride crystals. If the eyes or skin becomes contaminated with the
crystals, immediately consult a medical attention.
