Commissioning,

measuring, calibration TruLine

Commissioning,

measuring, calibration

Commissioning The combination electrode is filled with reference electrolyte solution in the

factory. Prepare the combination electrode for measuring as follows:
 Open the refilling opening for the reference electrolyte solution

The refilling opening must always be open during calibration and
measurement!

Refilling
opening

 Remove the watering cap from the electrode tip. Possible salt deposits in

the area of the watering cap do not affect the measuring characteristics
and can easily be removed with deionized water.

Calibration

and

measurement:

General

rules

Note

Please keep the watering cap. It is required for the combination electrode to
be stored. Always keep the watering cap clean.

 Calibrate the combination electrode according to the operating manual of

the meter and observe the following rules while doing so:

 Make sure the refilling opening for the reference electrolyte solution is

open.

 Avoid the displacement of any solution (sample or buffer solution) from

one measurement to the next by taking the following measures:
– Shortly rinse the calibration and sample beakers with the solution the

beakers are to be filled with next.

– Between measurements, rinse the combination electrode with the so-

lution that follows. Alternatively, you can also rinse the combination
electrode with deionized water and then carefully dab it dry.

 Immerse the combination electrode in the solution in a vertical or slightly

tilted position.

 Make sure the immersion depth is correct. The junction must be complete-

ly submersed in the solution. The junction is in the area of the bottom end
of the shaft (see figure). At the same time, the level of the reference elec­trolyte must be at least 2 cm above the level of the solution.

(Example)

 Provide approximately the same stirring conditions for measuring as for

calibrating.

Note
Prevent contact of the pH membrane to the beaker bottom to avoid scratches
on the pH membrane.

The frequency of subsequent calibrations depends on the application. Many
meters provide an option where you can enter a calibration interval. After the
calibration interval has expired, the meter will automatically remind you of the
due calibration.

Storage

With the refilling opening open, immerse the combination electrode in
reference electrolyte (KCl 3 mol/L, Ag

shortly rinse the combination electrode with the test sample or deionized
water.

Note
Prevent contact of the pH membrane to the beaker bottom to avoid scratches
on the pH membrane.

Put the clean combination electrode in the watering cap that is filled with
reference electrolyte (KCl 3 mol/L, Ag

Note
pH combination electrodes must not be stored dry or in deionized water. The
combination electrode could be permanently damaged by this. If the liquid in
the watering cap has dried up, condition the combination electrode in
reference electrolyte (KCl 3 mol/L, Ag+

Note

During longer storing periods, salt sediments may develop on the watering
cap. They do not affect the measuring characteristics and can easily be re­moved with deionized water when the combination electrode is put into oper­ation again.

ing, the responding behavior becomes slower and the electrode slope and
asymmetry change. Moreover, extreme operating conditions can consider­ably shorten the lifetime of the combination electrode. These are:

 Strong acids or lyes, hydrofluoric acid, organic solvents, oils, fats, bro-

mides, sulfides, iodides, proteins

 High temperatures
 High changes in pH and temperature.

The warranty does not cover failure caused by measuring conditions and
mechanical damage.

follows:

 Cut off the tip of the dropping bottle at a right angle until the opening in the

tip can be seen

 Open the refilling opening of the combination electrode
 Press the tip of the dropping bottle into the refilling opening while turning

it slightly

 Pump the reference electrolyte in the shaft using the dropping bottle
 Pull the dropping bottle out of the refilling opening while turning it slightly

if necessary.

Note

Hydrofluoric acid, hot phosphoric acid and strong alkaline solutions destroy

the glass membrane.

After cleaning Rinse the combination electrode with deionized water and condition it in

reference electrolyte solution for at least 1 hour. Then recalibrate the combi­nation electrode.
