Note

For ORP electrodes with platinum electrode, please observe the instructions in section A

Commissioning Prepare the combination electrode for measuring as follows:

CTIVATING PLATINUM ELECTRODES.

 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.

Note Please keep the watering cap. It is required for storing the combination electrode. Always keep the watering cap clean.

 Connect the combination electrode to the meter.  Measure with the combination electrode according to the operating man-

ual of the meter and observe the following rules while doing so:

General rules for

measuring

 TruLine ORP 51: Make sure the refilling opening for the reference electro-

lyte solution is open.

 Avoid displacement of the sample solution from one measurement to the

next by taking the following measures: – Briefly rinse the calibration beakers with the solution the beakers are to

be f illed with next.

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

lution specified below. 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 arrow).

The level of the reference

electrolyte

must be at least 2 cm above the level of

the solution.

(see page 11)

3 mol/l KCl, Ag+-free

Prior to the next measurement, briefly rinse the combination electrode with the test sample or deionized water.

Insert the clean electrode into the watering cap filled with reference electrolyte.

Note During longer storage periods, salt deposits 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.

Aging

Every ORP combination electrode undergoes a natural aging process. Extreme operating conditions can considerably shorten the lif etime of the combination electrode. These are:

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

mides, sulf ides, iodides, proteins

 High temperatures  Great changes in pH and temperature.

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

Activating platinum

electrodes

For the first-time activation use the activation powder from the SORT/RH reagent set (component of the SORT/RH reagent set). Immerse the moist (but not dripping) platinum electrode into the activation powder and rotate the electrode several times in the powder. Then remove the activation powder under flowing water with a soft brush (e.g. toothbrush).

Activation during

very long

set-up times

W hen changing from oxidizing to reducing test solutions and vice versa this can result in set-up times that can take significantly more than an hour. In this case pretreatment (activation) of the platinum surface can shorten the set-up time. The type of pretreatment (reducing or oxidizing) is based on the pH value and the ORP voltage (U timated for the f irst measurement.

) of the test solution where the latter must be es-

The type of pretreatment can then be determined using the following diagram where U
