Extended storage
When an electrode is not to be used for a long period of time, store the
electrode after performing the following steps. Also, replace the
reference solution every three to six months, using the method
explained below.
1.
Remove the electrode from the pH meter.
2.
Remove the protective cap from the electrode.
3.
Open the internal solution filler port and use a syringe to remove
the internal solution.
Chemical warning
The liquid inside the electrode is highly
concentrated potassium chloride (3.33 mol/L KCl).
If the internal solution in the electrode comes in
contact with your hands or skin, wash immediately
with water. If the internal solution comes in contact
with your eyes, flush immediately with large
amounts of water and seek treatment by a
physician.
