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.

 TruLine ORP 50: Open the refilling opening for the reference electrolyte

solution.

The refilling opening must always be open during 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.

General rules for

measuring

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:

 TruLine ORP 50: 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 filled 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.

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 and shut the refilling opening.

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 lifetime of the com­bination electrode. These are:

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

mides, sulfides, iodides, proteins

 High temperatures
 Great changes in pH and temperature.

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

Maintenance and cleaning

Refilling reference

electrolyte

Maintenance

and cleaning

During operation, a small amount of reference electrolyte leaks through the
junction from the combination electrode into the test sample. If the level of
reference electrolyte becomes too low with time, refill it through the refilling
opening.

Refilling is very easy using a dropper bottle. To do so, proceed as 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 dropper bottle into the refilling opening while turning it

slightly

 Pump several small quantities of the reference electrolyte into the stem

using the dropper bottle

 Pull the dropper bottle out of the refilling opening while turning it slightly if

necessary.

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).

When 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 first measurement.

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