●
Maintenance after daily use
After making measurements, wash the electrode using
pure water (deionized water), wipe off water from the
electrode with filter or tissue paper, and store it with its
cap placed on.
●
Long-term storage
When an electrode is not to be used for a long period of
time, store it after performing the following procedure.
Also, exchange the internal solution every 3 to 6 months,
using the steps explained below.
1.
Disconnect the electrode from the instrument.
2.
Detach the protective cap from the electrode.
3.
Open the internal solution filler port, then use a
dropper to remove the internal solution.
CAUTION
Harmful chemicals
The internal solution of an electrode is highly concentrated potassium chloride
(3.33 mol/L KCl).
If the internal solution comes in contact with the skin, wash it off immediately. If it
gets into eyes, flush with plenty of water and then consult a doctor.
