4110(W) General information

1 General information

Automatic sensor

recognition

The sensor electronics with the stored sensor data are in the connecting
head of the electrode. The data include, among other things, the senso r type
and series number. In addition, the calibration data are stored in the sensor
with each calibration and the calibration history is recorded (the last 10 cali­brations). The data is recalled by the meter when the sensor is connected
and is used for measurement and for measured value documentation.

Storing the calibration data in the sensor ensures that the correct slope and
asymmetry are automatically used if the sensor is operated with different
meters. On the other hand, different calibrated sensors can be used with one
meter without the need to recalibrate.

The digital transmission technique guarantees the failure-free communica­tion with the meter even with long connection cables. The sensor firmware
can be updated via the meter.

2.1 Commissioning

Scope of delivery  Electrode 4110(W)

 Operating manual

Commissioning Prepare the electrode for measuring as follows:

 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.

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

 Remove any gas bubbles behind the pH membrane by shaking.
 Connect the electrode to the meter.

4110 – via the sensor cable to a free IDS connec-

tor on the meter

4110W – via a connecting cable (accessory) to a

free IDS connector on the meter

or
– wireless via an IDS WA-S adapter (acces-

sory) to a WA-capable meter

 If necessary, clean the plug connection.
 Open the locking device (step 1).
 Use your thumb and index finger to press the clips of the connector

together, and pull the connector out of the plug (step 2).

 Make sure that the plug connection is completely dry and clean.
 Align the guidance of the connector with the groove in the plug and insert

the connector in the unlocked plug until it catches (step 3).

 Close the locking device (step 4).

Storage 4110(W)

2.3 Calibration and measurement: General rules

 Avoid the carryover 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 electrode with the solution that fol-

lows. Alternatively, you can also rinse the electrode with deionized
water and then carefully dab it dry.

 To measure in aqueous solutions, it is recommended to immerse the elec-

trode in a vertical or slightly tilted position.

 Observe the correct depth of immersion and make sure the contact

between the junction and test sample is thorough. The junction is in the
area of the bottom end of the shaft (see arrow).

Subsequent

calibrations

During short

measuring breaks

4110(W)

Caution: Only the shaft part of the electrode may be immersed!

 For measurements in aqueous solutions, provide approximately the same

stirring conditions for measuring as for calibrating.

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.

3Storage

Immerse the electrode in reference electrolyte (KCl 3 mol/l, Ag+ free). Prior
to the next measurement, shortly rinse the electrode with the test sample or
deionized water.

Do not scratch the pH membrane.

Overnight or

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

NOTE

pH electrodes must not be stored dry or in deionized water. The elec­trode could be permanently damaged by this. If the liquid in the
watering cap has dried up, condition the electrode in reference electro­lyte (KCl 3 mol/l, Ag+ free) for at least 24 hours.

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 elec­trode is put into operation again.

free).

4 A ging

pH electrodes are consumables. Every pH electrode undergoes a natural
aging process. With aging, the responding behavior becomes slower and the
electrode slope and asymmetry change. Moreover, extreme operating condi­tions can considerably shorten the lifetime of the 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.

5 Maintenance and cleaning

Cleaning Remove water-soluble contamination by rinsing with deionized water. Other

types of contamination have to be removed as follows while the contact time
with the detergents should be kept as short as possible:

Contamination Cleaning procedure

Fat and oil Rinse with water containing household wash-

ing-up liquid

Lime and hydroxide deposits Rinse with citric acid (10 % by weight)

NOTE

Hydrofluoric acid, hot phosphoric acid and strong alkaline solutions
destroy the glass membrane.

After cleaning Rinse the electrode with deionized water and condition it in reference elec-
