Product handling information
Operational precautions
Use of the product in a manner not specified by the manufacturer may
impair the protection provided by the product. And it may also reduce
product performance.
Exercise the following precautions:
Use the supplied internal solution for the reference electrode. Using any
other internal solutions may cause measurement errors.
If the ion selective membrane is dry, soak the electrode in pure water for
at least one hour. Using it in a dry state will cause measurement errors.
Do not get the electrode connector wet or touch it with dirty hands. It may
cause a failure.
Do not touch a hard surface with the electrode. It may cause a failure.
Only use the product including accessories for their intended purpose.
HORIBA Advanced Techno assumes no liability when they are used for
any other products.

Product features
System configuration
The combination type potassium ion selective electrode is an electrode that
combines a tip type ion electrode with a reference electrode.
This product has the following features.
Ion concentration can be measured with this one electrode. There is no
need to use a pair of an ion selective electrode and reference electrode.
The reference electrode part has a double junction structure. This
minimizes the contamination of the sample solution by the internal
solution outflow, the interference on the electrode potential, and so on.
Since the structure of the liquid junction, movable sleeve type, is capable
of eliminating clogging by contaminants, it is possible to measure the
concentration accurately.
This product is used with the meter of HORIBA Advanced Techno
connected, which is sold separately.
Electrode stand(*) is also available.
Refer to the meter instruction manual for more details.

NoteNote
Internal solution Dropper
Items to be prepared
Be sure to fill the electrode with internal solution as
described in the following procedure before use.
Be sure to fill with internal solution before
use.
If measurement is performed in the state in
which there is not much internal solution,
an inflow of sample solution into the
electrode will result in accurate
measurements no longer being possible.
Use the internal solution included in the
package or available as a consumable sold
separately by HORIBA Advanced Techno.
( “Consumables” (page 70))
Discharge the internal solution each time
measurement finishes.
1 Remove the protective cap.
(Except when it is already removed,
such as first time of use.)

NoteNote
If there is any internal solution remaining, remove it all.
( Steps 1 to 2 of “How to clean the electrode” (pages 38 to 39.))
3 Open the rubber stopper of the
internal solution fill port.
4 Fill the internal solution with a
dropper.
Fill until the solution surface comes up to just
below the internal solution fill port.
5 Spread soft and clean lint-free paper or cloth beneath the
electrode and then press the electrode against it from
above.

When pressing the electrode from above, do not press too

down and that internal solution oozes out from the liquid
junction.
The internal solution
oozes out from the
liquid junction.
It is best that the internal solution oozes out slightly. If the
outflow is extremely little, the potential of the reference electrode
will become unstable and susceptible to stir.
In such a case, repeat step 5 and 6 until the internal solution
oozes out from the liquid junction.

Contamination
NoteNote
Make sure that no dirt and other foreign matters have
adhered to the electrode before measurement.
If dirt and other foreign matters have adhered to the
electrode, rinse the electrode as described in the following
procedure.
1 Rinse the electrode with pure water.
2 Wipe off the moisture.
Wipe off the moisture using soft and clean lint-free paper or cloth.
3 Make sure that there are no dirt and
crystals of internal solution adhered
to the area around the liquid
junction.
If dirt and crystals of internal solution are adhered, they
may affect the outflow of internal solution. Rinse the
electrode with pure water again.
