Product overview
The 2100AN IS laboratory turbidimeter measures turbidity in FNUs
(Formazin nephelometric units), NTUs (nephelometric turbidity units) and
EBCs (European Brewing Convention units). NTUs and EBCs are
calculated using the conversion factors of 1.0 NTU per 1.0 FNU and
0.245 EBCs per 1.0 FNU. The 2100AN IS turbidimeter also measures
attenuation (FAU), absorbance and transmittance.
In addition, two user-defined measurement units can be specified. The
application specific mode of operation uses the nephelometric optical
system and the NTU measurement mode.
The turbidimeter has a built-in printer and an RS232 output for
connection to a printer, data logger or computer and a recorder output.
The turbidimeter contains a real-time clock with battery. The clock
provides a time-date stamp on all data transmitted to the built-in printer
or to external devices by way of the RS232 interface (i.e., measurements
and calibration records).

Standard operation
Calibrate the turbidimeter with StablCal® Standards
Calibrate the turbidimeter before it is used for the first time using the
StablCal® sealed vial standards provided. As an alternative, calibration
can be done with recently prepared formazin standards.
Calibrate the turbidimeter at least every 3 months or as specified by the
regulating authority when data is used for ISO 7027 reporting.
Note: Unknown results may occur if standards other than the recommended
calibration points are used. The recommended calibration points (< 0.1, 20, 200,
1000, 4000 and 7500 NTU) provide the best calibration accuracy. Use of standards
other than StablCal, or user-prepared formazin, may result in less accurate
calibrations. The manufacturer cannot guarantee the performance of the instrument
if calibrated with co-polymer styrenedivinylbenzene beads or other suspensions.
Prepare the StablCal standards
When received and at intervals:
1. Clean the exterior surface of the StablCal vials with laboratory glass
cleaning detergent.
2. Rinse the vials with distilled or deionized water.
3. Dry the vials with a lint-free cloth.
Note: Never shake or invert the < 0.1 NTU standard. If the standard has been
mixed or shaken, do not move the vial for 15 minutes or more before using.
Note: Do not remove the caps from the sealed vials.
Make sure that the StablCal standards are at ambient instrument
temperature before use (and no greater than 40 °C (104 °F)).
Mix the standards before use:
1. Open the case lid. Remove the < 0.1 NTU standard from the plastic
case.
2. Leave the other standards in the case. Close the case lid.
3. Shake the case vigorously for at least 10 seconds.
4. Let the standards stand with no movement for 3–5 minutes before
use.
Calibration notes
• Make sure that the instrument is in the same ambient conditions as
where it is used.
• Make sure that the standards are at the same ambient temperature as
the instrument before use.
• Use only the provided silicone oil. This silicone oil has the same
refractive index as the vial glass and masks minor glass differences
and scratches.
• Store the oiling cloth in a plastic storage bag to keep the cloth clean.
• If power is lost during calibration, the new calibration data is lost and
the last calibration data is used. To exit a calibration and not save the
new values, push UNITS/Exit.

Turbidity measurement
W A R N I N G
Potential explosion and fire hazard. This instrument is for measuring water based
samples. Do not measure solvent or combustible based samples.
For accurate turbidity readings use clean sample cells and remove air
bubbles.
Measurement notes
Proper measurement techniques are important in minimizing the effects
of instrument variation, stray light and air bubbles. For accurate and
repeatable measurements:
Instrument
• Make sure that the instrument is on a level, stationary surface that is
free of vibration during the measurement.
• Instrument stabilization is immediate. No warm-up time is necessary.
• Always close the sample compartment lid during measurement,
calibration and storage.
• Remove the sample cell from the instrument and turn off the
instrument if the instrument is stored for an extended time period
(more than a month).
• Keep the sample compartment lid closed to keep dust and dirt out.
Sample cells
• Always cap the sample cell to prevent spillage of the sample into the
instrument.
• Always use clean sample cells in good condition. Dirty, scratched or
damaged cells can result in readings that are not accurate.
• Make sure that cold samples do not “fog” the sample cell.
• Store sample cells filled with distilled or deionized water and cap
tightly.
English13
• For the best accuracy, use a single sample cell for every
measurement or a flow cell.
Note: As an alternative, matched sample cells may be used for measurements but
do not provide as good of accuracy or precision as a single indexed sample cell or
flow cell. When using matched sample cells, align the orientation mark on the
sample cell with the reference mark on the sample cell holder.
Measurement
Turbidity measurement procedure
• Measure samples immediately to prevent temperature changes and
settling. Before a measurement is taken, always make sure that the
sample is homogeneous throughout.
• Avoid sample dilution when possible.
• Avoid instrument operation in direct sunlight.
1. Rinse a clean,
empty sample cell two
times with the solution
to be measured and
drain to waste. Fill to
the line (about 30 mL)
with sample and
immediately put the cap
on the sample cell.
14 English
2. Clean the sample
cells with a soft, lint-free
cloth to remove water
spots and fingerprints.
3. Apply a small bead
of silicone oil from the
top to the bottom of the
sample cells.
4. Use the oiling cloth
provided to apply the oil
equally to the surface of
the sample cells.
Remove the excess oil.
Make sure that the
sample cells are almost
dry.
5. Gently and slowly
invert the sample cell to
fully mix the sample. Be
careful not to add air
bubbles.
6. Put the sample cell
in the sample cell
holder with the triangle
on the sample cell
aligned with the
reference mark on the
sample cell holder.
Close the cover.
7. Read and record the
value when stable.
Note: To print or send
(via RS232) a
measurement record,
push PRINT.
Measurement techniques
Measurements may be made with different operation mode settings and
optional accessories.
Calibrate the instrument whenever the sample cell pathlength is
changed.
Manual or automatic ranging
The manufacturer recommends that ranging be set to automatic for most
measurements.
The setting can be changed at any time during sample measurement.
Push RANGE repeatedly to step the instrument from automatic ranging
to manual ranging and then scroll through the manual range settings.
"MANUAL" is shown above the Range Mode label on the instrument
when manual ranging is selected. "AUTO" is shown below the Range
Mode label on the instrument when automatic ranging is selected.
Notes:
• When manual ranging is selected, the display flashes all 9s when the
sample being measured is greater than the selected range. The
display flashes all 0s when the sample measured is less than the
selected range.
• When automatic ranging is selected, the display flashes 9s when the
sample is greater than the maximum range of the instrument. The
display flashes 9s when Ratio is off and the measurement is greater
than 40 NTUs (1000 FNUs or 9.8 EBCs). Turn Ratio on to increase
the range.
• When automatic ranging is selected, the display flashes all 0s when
the measurement is less than the range of the instrument (i.e., less
than 20 FAU) or a negative value. Calibrate the instrument. When
measuring absorbance or transmittance, set the zero reference point
again.
Signal averaging on or off
Signal averaging corrects for reading fluctuations that are caused by
random drifting particles in the sample. When signal averaging is on, an
average reading is calculated every 3 seconds and shown on the
display.
The manufacturer recommends that signal averaging be on for most
measurements.
Push SIGNAL AVG to turn signal averaging on or off. The SIGNAL AVG
light turns on when signal averaging is on.
English15
Push ENTER when signal averaging is on to erase data in the signal
averaging buffer and provide an immediate update on the display as
necessary. This is especially useful when measuring samples with large
differences in turbidity.
To change the number of measurements that are used to calculate the
average reading (default=10):

Ratio on or off
Ratio on provides very good linearity, calibration stability and a wide
measurement range. Ratio on helps correct for interference when color
is present in the sample that absorbs at the wavelength of incident light.
The manufacturer recommends that Ratio on be used for most
measurements. Ratio must be on to measure samples greater than
40 NTUs (9.8 EBCs).
Ratio can be turned on for NTU, EBC and ASC -1- and -2measurements.
Push RATIO to turn Ratio on or off. The Ratio light is on when Ratio is
on.
Notes:
• If the sample being measured is greater than 40 NTU (or equivalent)
and Ratio is off, the display will show 9s and the RATIO light will flash.
Push RATIO to turn Ratio on and remove the over-range condition.
• Measurements with Ratio on and measurements with Ratio off are
almost the same for turbidity measurements that are less than 40 NTU
if interferences caused by color or light absorbing particles are not
present.

Produktübersicht
Das 2100AN IS-Labor-Trübungsmessgerät misst Trübung in FNUs
(Formazin Nephelometric Units), NTUs (Nephelometric Turbidity Units)
und EBCs (European Brewing Convention Units). NTUs und EBCs
werden mit den Umrechnungsfaktoren 1,0 Nephelos pro 1,0 NTU und
0,245 EBCs pro 1,0 FNU berechnet. Das 2100AN ISTrübungsmessgerät misst außerdem Attenuation (FAU), Extinktion und
Transmission.
Zusätzlich können zwei benutzerdefinierte Messeinheiten festgelegt
werden. Der Kalibrierpunkte Betriebsmodus verwendet das
nephelometrische optische System und den NTU-Messmodus.
Das Trübungsmessgerät hat einen integrierten Drucker und einen
RS232-Ausgang zum Anschluss an einen Drucker, Daten-Logger oder
Computer und einen Schreiberausgang.
Das Trübungsmessgerät beinhaltet eine Echtzeituhr mit Batterie. Die
Uhr versieht alle Daten, die an den integrierten Drucker oder an externe
