What does a perfect a) electrode
look like?
The ∆KCl•L solution must
be less than 5 mm below
the filling hole.
When needed, top up with
∆KCl•L.
0.5 cm
When the electrode is
turned upside down, the
∆KCl•C crystals should
move down through the
liquid as small crystals. If
necessary, carefully shake
the electrode or tap the
electrode stem in your
hand to loosen the ∆KCl•C.
Afterwards, check point 4.
Crystal deposits around
the filling hole should be
removed with wet paper
tissue.
For a) electrodes (different geometry for b) c)
and d) electrodes)
Porous, ceramic pin. The ceramic pin is
white when the electrode is new, but in
use it often gets discoloured ('black'). The
black discolouring will, under normal
circumstances, not harm the functioning
of the electrode. As long as the electrode
is cleaned regularly with
and/or
RENOVO•X, problems will be
minimised.
5 mm of ∆KCl•C crystals
must be present in the
refillable inside part at the
measuring temperature.
Refill with ∆KCl•C crystals
0.5 cm
when needed. Without
∆KCl•C crystals the results
may drift.
Air bubbles must not be
present anywhere inside
the electrode. Air bubbles
result in a fluctuating or
drifting electrode potential.
To remove air bubbles, see
the ∆KCL•l & ∆KCl•C
Card, illustration 15.
The filling hole must be
covered when the electrode
is left overnight. For
GK2401, use the black
rubber stopper.
The filling hole must be
open during measurement.
The clip can be ordered
under part no. 905-301
(25 pcs).
