4.5 Turbidity
4.5.1 General information
Venting the sample Air bubbles in the sample affect the measuring result to a massive
extent because they have a large scattering effect on the incident light.
Larger air bubbles cause sudden changes in the measured values
whereas smaller air bubbles are recorded by the instrument as
turbidity. Therefore, avoid or remove air bubbles:
Avoiding or removing
air bubbles
Aligning the cell
! During sampling, ensure all movement is kept to a minimum
! If necessary, vent the sample (ultrasonic baths, heating or adding a
surface-active substance to reduce the surface tension)
Note
For turbidity values under 1 FNU/NTU, follow the instructions given in
the appendix (see A
PPENDIX: TURBIDITY VALUES UNDER 1 FNU/NTU).
4.5.2 Aligning and marking a cell
Even perfectly clean quality cells exhibit tiny directional differences in
their light transmittance. Therefore, if you want to achieve accurate and
reproducible measurement results, it is necessary to always index the
sample cells and cells for calibration standards in the same way (see
section 2130 of "Standard Methods for the Examination of Water and
Wastewater", 19th edition).
To do so, the optimum alignment of the cell is determined.
1 Clean the cell (see section 5.2.2).
ba75507e03 07/2006
2 Insert the cell (see section 4.2).
3 Align the cell:
! Press and hold the <START/ENTER> key.
! Slowly and in small steps rotate the cell by one complete
rotation (by 360 °).
After each step wait for a short time until the displayed
measured value is stable.
! Turn the cell back to the position with the lowest measured
value.
Note
To keep the drift as low as possible, the time for aligning the cell while
pressing and holding the <START/ENTER> key is limited to 30
seconds. After this time, the meter starts measuring automatically.
33
Operation Turb 430 IR/T
4 Release the <START/ENTER> key.
Measurement starts. The measured value is displayed.
Marking a cell To be able to quickly bring a cell into the optimum position, it is helpful
to mark the optimum position of the cell once it is determined. This
shortens each measurement or calibration procedure with this cell
considerably.
The marking can, e. g., be done on a label on the cap of the cell.
5 Mark the optimum position of the cell.
The cell is prepared for the shortened measuring and
calibration procedures.
Measuring
4.5.3 Measuring turbidity
Caution
Never pour any liquids directly into the cell shaft. Always use a
cell for measurement. The meter only measures precisely if the
cell is closed with the black light protection cap (WTW cells).
Note
The outside of the cell always has to be clean, dry, and free of
fingerprints and scratches. Clean the cells before starting to measure
(see section 5.2.2). Only hold the cells by the top or by the black light
protection cap.
1 Rinse out a clean cell with the sample to be measured:
Pour approximately 10 ml sample into the cell. Close the cell
and rotate it several times before throwing the sample away.
2 Repeat the rinsing procedure twice more.
3 Fill the cell with the sample to be measured (approx. 15 ml).
Close the cell with the black light protection cap.
4 Clean the cell (see section 5.2.2).

4.7 Transmitting data (RS 232 interface)
Via the RS 232 interface, you can transmit data to a PC or an external
printer.
The data can be transmitted to a PC, for example, with the aid of a socalled terminal program.
Generally, a terminal program serves to establish a connection to a
device on a data interface and to communicate with the device via a
console on the display. A terminal program usually offers the possibility
to save the contents of the console in a text file or print it. If the terminal
program is connected to the meter, it can receive data from the meter
and display it on the console.
Terminal programs are available for different operating systems by
different manufacturers. Windows (version 95 to XP) contains the
"HyperTerminal" terminal program. It is in the program menu under
Accessories.
For more detailed information please refer to the user information of the
terminal program.
The settings required for the use of the "HyperTerminal" program are
given in section 4.7.1.
Note
When using the "HyperTerminal" program you can load the
transmission data automatically using the *.ht file provided on the CD.

5.2 Cleaning
Occasionally wipe the outside of the meter with a damp, lint-free cloth.
Disinfect the housing with isopropanol as required.
Caution
The housing components are made out of synthetic materials
(polyurethane, ABS and PMMA). Thus, avoid contact with acetone
and similar detergents that contain solvents. Remove any
splashes immediately.
5.2.1 Cleaning the cell shaft
If liquid is in the cell shaft (e.g. due to a spilled cell), clean the cell shaft
as follows:
1 Switch the Turb 430 IR/T off and pull out the power plug.
2 Rinse the cell shaft with distilled water.
5.2.2 Cleaning the cells
Cells have to be clean, dry, and free of fingerprints and scratches.
Therefore, clean them regularly:
1 Clean the cells inside and out with hydrochloric acid or
laboratory soap.
2 Rinse out several times with distilled water.
3 Let them dry in the air.
4 Only hold the cells by the top or by the light protection cap so
that the optical path is not impaired.

Glossary
Adjusting To manipulate a measuring system so that the relevant value (e. g. the
displayed value) differs as little as possible from the correct value or a
value that is regarded as correct, or that the difference remains within
the tolerance.
Calibration Comparing the value from a measuring system (e. g. the displayed
value) to the correct value or a value that is regarded as correct. Often,
this expression is also used when the measuring system is adjusted at
the same time (see adjusting).
Cell Vessel that takes a liquid sample for measurement.
LED Light Emitting Diode
LEDs are used as the light source in the Turb 430 IR/T.
Measured parameter The measured parameter is the physical dimension determined by
measuring, e. g. pH, conductivity or DO concentration.
Measured value The measured value is the special value of a measured parameter to
be determined. It is given as a combination of the numerical value and
unit (e. g. 3 m; 0.5 s; 5.2 A; 373.15 K).
Measuring system The measuring system comprises all the devices used for measuring,
e. g. meter and sensor. In addition, there is the cable and possibly an
amplifier, terminal strip and armature.
Molality Molality is the quantity (in Mol) of a dissolved substance in 1000 g
solvent.
Reset Restoring the original condition of all settings of a measuring system.
Resolution Smallest difference between two measured values that can be
displayed by a meter.
Standard solution The standard solution is a solution where the measured value is
known by definition. It is used to calibrate a measuring system.
Test sample Designation of the test sample ready to be measured. Normally, a test
sample is made by processing the original sample. The test sample
and original sample are identical if the test sample was not processed.

Appendix: Turbidity values under 1 FNU/NTU
With turbidity values (under 1 FNU/NTU), the measured value is
strongly influenced by the cell and its alignment.
In order to increase measuring accuracy with turbidity values under 1
FNU/NTU, calibration in the 0.02 FNU/NTU standard and later
measurement should be carried out in the same cell. For calibration in
the standards 10.0 and 1000 FNU/NTU follow the instructions on the
display.
Proceed as follows to measure turbidity values under 1 FU/NTU:
Calibration procedure:
Measuring
1 Press the <CAL/ZERO> key.
The menu-guided calibration begins.
2 Carry out calibration of the standards 1000 FNU/NTU and
10.0 FNU/NTU in a clean and unscratched cell according to
the menu guidance.
3 Fill the cleaned cell with the 0.02 FNU/NTU standard and
calibrate.
4 Mark the alignment of the cell.
Calibrate
! after the calibration interval has expired
! with a temperature change
5 Fill the marked and cleaned cell with test sample, align it
with the marking and measure.
6 If necessary, fill the marked and cleaned cell once more
with test sample and carry out further measurements.
