Inputs
The measuring electrode should be connected to the coaxial INPUT connector. If
separate electrodes are used, connect the reference electrode to the REF. ter-
minal. Automatic temperature compensation and temperature measurements are
possible by plugging a Pt1000 temperature probe into the °C terminals. You can
also use a combination pH electrode with built-in Pt1000. Its banana plugs should
be inserted in the °C terminals. Without Pt1000, the manual temperature compen-
sation is automatically switched on.

Interferences
All substances which can diffuse through the membrane and for which 800 mV poten-
tial suffices for polarographic reduction, will be reduced in the electrode. This will
give a corresponding current contribution, if they are present. Interference can
be caused by ions entering the electrode through porous or mechanically damaged
membranes and by diffusion of other reactive gases apart from oxygen, e.g. CO
2
,
Cl
2
, SO
2
, and H
2
S. These substances react in undesired manner with the electrode.
Acidic or basic gases change the pH value of the electrolyte solution and thus dis-
turb the reading, particularly when measuring small oxygen concentrations. High
salt concentrations in the sample solution can falsify readings too.
salt concentrations in the sample solution can falsify readings too.
Principle
Principle
The oxygen meter and its electrode function according to the Clark principle with
silver as cathode and lead as anode in an electrolyte cell. Oxygen gas present
in the electrolyte is reduced to OH ions at the cathode. The resulting current is
diffusion limited and therefore proportional to the oxygen concentration in the
sample solution. This current is amplified, corrected, and displayed in mg/l, ppm
or % dissolved oxygen.

Maintenance of pH electrodes
Maintenance of pH electrodes
A pH electrode is active and stable only after wetting!
For this purpose it must
be immersed for
at least ten hours
in a 3...4 M KCl solution. During short inter-
ruptions (e.g. storage) the electrode should be immersed in a 3...4 M KCl solution.
In doing this it is always kept ready for use. When the interruption is longer than
a month, refill the closing cap with 3...4 M KCl and plug it on the electrode tip in
order to protect the glass bulb. Before use, ensure that the reference part of the
electrode is topped up with a 3...4 M KCl solution.
Avoid a low pressure inside the electrode!
Therefore always remove the closure
from the refilling aperture during the measurements as well as during the calibra-
tion. This allows the saltbridge solution to flow through the ceramic liquid junction
and prevents contamination of the electrolyte. For the same reason, the inside
level should always be higher than the outside level of the measuring solution.
Close the refilling aperture again when storing the electrode.
A polluted electrode may be cleaned with a soft detergent or 0.1 M HCl. Greasy
substances may be removed with acetone or alcohol
(never do this with plastic
electrodes!)
.
If the electrode is polluted by proteinaceous materials (such as blood), it should
stand in a cleaning solution overnight and then be cleaned with distilled water
before use. The pH electrode wears away by being used. If the electrode tends to
respond slower and calibration becomes difficult, even after cleaning, it should be
replaced by a new one.
replaced by a new one.
Maintenance of oxygen electrodes
Maintenance of oxygen electrodes
A dissolved oxygen electrode is active and stable only when polarised!
The
electrode body has almost unlimited life and requires no maintenance. After pro-
longed use of the electrode, it may become deactivated. An indication is that the
electrode no longer responds correctly to calibration. In this case:
1.
Carefully screw off the measuring head.
2.
Cautiously remove the precipitated deposits with the aid of filter paper.
Do
not use grinding paper or a glass fibre!
3.
Rinse several times with distilled water and shake carefully off the water
drops.
4.
Take the measuring head, fill it with new electrolyte solution and very slowly
screw it onto the electrode while holding it vertically.
5.
Let the electrode rest for a few hours!
The electrode is now ready for use
again.
•
Replace the membrane only when damaged, not when calibration is no longer
possible!
Maintenance of metal electrodes
Maintenance of metal electrodes
Metal electrodes (Pt, Ag, Au):
Metal electrodes are always ready for use. During
short interruptions they are immersed in distilled water.
They should be cleaned
regularly:
•
Silver electrodes are immersed in a concentrated ammonia solution during one
hour.
•
Platinum or gold electrodes are immersed in concentrated nitric acid during
one hour.
Maintenance of conductivity electrodes
Maintenance of conductivity electrodes
A conductivity cell is active and stable only after wetting!
For this purpose it
must be immersed for
at least one hour
in distilled water. Rinse the cell always
after use and store it in distilled water (add some detergent to keep the spongy
platinum surface in perfect condition).
A polluted cell may be cleaned with a soft detergent or diluted nitric acid. Greasy
substances may be removed with acetone or alcohol (never do this with plastic
electrodes!).
