Maintenance

5.
Rinse the electrode
with deionized
water or tap water
after each
measurement.
In aggressive chemicals, dirty, or
viscous solutions, and solutions with
heavy metals or proteins, take
readings quickly and rinse the
electrode immediately after use.
Periodic soaking in
warm pH 4 buffer
will help remove
any contaminants
that will ruin the
electrode.
Keep a small piece of paper or
sponge, moistened with tap water
or pH 4 buffer, in the Testr cap to
keep the probe moist during
storage.
Electrode life will be shortened
when a Testr is used in applications
where the electrode is exposed to
materials that will contaminate the
electrode reference junction.
