Maintenance

1. After each working cycle, the sensitive part can
be cleaned with a soft toothbrush and a diluted
HCl-solution (0.1 and 1 mol/L), and then rinsed
with 20% NaCl solution.
2. If the electrode is not in use it must be stored with
the electrode tip immersed in Buffer pH = 4.01 / Na
3.9M.
3. If an electrode is inadvertently stored in a dry con-
dition for several days, the membrane must be im-
mersed in Buffer pH = 4.01 / Na
6 hours.
4. The plug-in head should occasionally be checked
for possible traces of moisture. If necessary, clean
it thoroughly with deionized water or alcohol and
then dry it off carefully.

age the pH sensitive part of the electrode.
