A Instrument Description
A1 General
LICO® 100 is a universal colorimeter for liquids suitable for manifold industrial applications. It is easy
to handle and has a sturdy design.
But what is really the reason why objective color measurement of liquids is so important? The human
eye is able to perceive about 100 spectral colors in approximately 100 degrees of brightness and
saturation, which results in about 1 million perceptible shades. Therefore, hues are difficult to describe
by subjective visual comparison.
The specific color of a product is often regarded as a sign of purity and quality, although that is not
necessarily true. Clients often interpret deviations from the shade of an earlier production as defective
product or supply and reject it preventively. In order to avoid such trouble, objective color assessment,
a uniform colorimetric system and reliable instrument are required for production and quality control of
transparent colored liquids.
New Standard EN 1557
EN 1557 (Colorimetric characterization of transparent colored liquids) now also defines color
measurement of liquids on the basis of the time-tested colorimetric standards of DIN 5033. The
principle is to measure the X-, Y- and Z-transmissions. The sample is illuminated with a halogen lamp
corresponding to standard illuminant C. On this basis, Koehler developed the LICO® 100 for exact and
reproducible measurements of transparent yellow-cast liquids.

A2 Instrument Design
LICO® 100 measures transmissions of all transparent media. It operates with a halogen lamp
producing standard illuminant C and uses the 2° standard observer as defined by DIN-standard 5033.
A reference beam path compensates measuring values modified by driftings of lamps and
temperatures during operation. Therefore, LICO® 100 provides an excellent long-term constancy and
reproducible measuring results. The universal cuvette compartment suitable for 50 x 10mm square
cuvettes and 11mm round glass cuvettes permits an optimum adaptation of LICO® 100 to the
measurement tasks.
In just one measurement, LICO® 100 evaluates by to the latest ISO-standards giving e.g. Iodine, Hazen
or Gardner values. The basical instrument includes one optional color number with the possibility of
adding-on a random combination of color numbers later or at once. These color systems are
available: Iodine number, Hazen number, Gardner number, Saybolt number and ASTM D 1500 number.
To add-on more color systems later, a program-module-box (bit-box) is supplied. The description of
this bit-box is given in chapter D6.

A3 Instrument Set-Up
Unwrap the instrument carefully and check it for missing parts (delivery note). Please keep the packing
box to pack the instrument safely in case it has to be transported again later.
LICO® 100 should be placed on a level desk surface. The instrument comes with a power supply unit
and adapter for the socket (100 – 240 Volt / 47 – 63 Hz) and is turned on by either pressing the OK-
key or the grey menu key.
Do not turn on and off too fast. Wait for 20 seconds before turning on again not to damage the
electronic or mechanic system of the instrument.
The blue lamp protection cover on the upper left part of the instrument serves to carry the heat off
the lamp and must not be covered.
As LICO® 100 is a sophisticated optical instrument, avoid the following at any rate:
• Do not use the instrument in direct sunlight.
• Do not allow water, inflammable or metallic objects to enter the instrument.
• Do not put filled cuvettes or heavy objects on the housing.
• Do not use the instrument in excessively moist, dusty or vibrating surroundings.
• Do not open the instrument. There are no parts in the housing for the user to check.
• If you have any questions of problems, please contact Koehler’s Technical Service
Department.
A4 Reference Standards
In general, an absolutely transparent medium similar to the sample serves as a calibration or reference
standard for colorimetry on the transmission principle. To measure the color of liquids, distilled water is
filled into a cuvette similar to the measuring cuvette and used as a reference standard. In some
exceptional cases where the density of the substance to be measured differs from that of the distilled
water, calibration is made against a colorless measuring medium. Calibration assigns the reference
standard a transmission of 100% (or Iodine number = 0, Hazen = 0, etc.). As this assignment never
changes, 100 no calibration value needs to be set for LICO®. Instead, just fill a cuvette with the
reference standard and put it into the cuvette compartment to perform calibration.

B4 Battery ModeLICO® 100 can be used with power supply unit or rechargeable batteries. For the latter mode, open
the cover of the battery compartment and insert the batteries as follows:
1. Insert the battery with the switch to the right into the holder until only one contact remains visible.
2. Shift the battery from the left side over the contacts, passing a slight resistance.
3. A beep indicates that the batteries are placed and ready for operation (only when the instrument
is not connected to the mains).
Attention: The contacts must not get into contact with metal or greasy parts.
To recharge the batteries, insert them into the compartment and connect LICO® 100 to the mains with
the power supply unit. We recommend a continuous loading time of 14 hours before the first use. To
exploit the battery capacity best, charge and discharge it always entirely. The display of LICO® 100
informs about the current discharge degree of the battery when the instrument is turned on. When the
battery is discharged, a beep and a display message are given. The message must be acknowledged

with the grey menu key to go on working for a short while. The display message “battery empty” means
that the battery is definitely discharged and needs recharging.
B5 Turning-OffLICO® 100 turns off automatically by a timer function. Manual turning-off is possible, too.
Manual Turning-Off
Press Cursor-Key & in the measuring menu and select option
„Switch Offf“ with the OK-key. Then the instrument turns off.
Turning-Off Via Timer
On delivery, the timer of LICO® 100 is set to automatic turning-off
time of 30 minutes. The automatic turning-off is only active if no
measurement was made within the given period and no cuvette is
in the compartment. The setting can be modified within the tolerances of 10 to 60 minutes.
B6 Photometric PreparationThe photometric preparation requires utmost care, because careless sample preparation is the major
source of trouble, and not the handling of the instrument itself.
Cleanliness is of vital importance in photometry. Therefore, clean the glass cuvettes immediately after
use. Employ only optically perfect samples for measuring. They must be clean and not show any signs
of opaqueness.
Air bubbles in the sample or at the cuvette sides influence the measuring result. They can be avoided
by filling the liquid slowly into the cuvette. Pasty or solid products should be melted and filled-in without
bubbles, if they cannot be measured as they are.
B6.1 Sampling And Sample Preparation
Take a sample from the product you want to measure in accordance with DIN 53242 part 1. Eliminate
turbidities by heating or filtration. Heat partly solid samples before measuring in order to dissolve the
solid share in the liquid one. The preparation must not cause any chemical changes in the sample.
During the measurement there should be no bubbles in the sample.1
• There are several cuvette types available for color measurement with LICO® 100, differing by
material (glass, polystyrene or PMMA2) and path length (11mm and 50mm).

• The program calculates automatically Iodine, Hazen, Gardner, Saybolt and ASTM D 1500-
numbers under consideration of the cuvette type employed.
• For the 11mm disposable round glass cuvettes, a dry thermostat is available to warm up to 15
cuvettes to 100°C or 148°C.
C Color Measurement
Whenever the instrument is turned on, a zero measurement is made, taking the empty value (i.e. the
pure transmission values without cuvette inserted) of the optical beam path and comparing it with the
empty value obtained in the previous zero measurement. If the difference between both empty values
is near zero, you can start measuring without calibration. Calibration is only required in case of
considerable deviations of the empty value due to e.g. fluctuations of temperature. The calibration
remains valid until the next recalibration. LICO® 100 features a calibration memory for both path
lengths employed (50mm square cuvette and 11mm round cuvette). If you have to use two different
path lengths, owing to the nature of your samples (e.g. bright samples with Hazen values below 50 or
strongly colored samples with greater Gardner values), it is possible to calibrate both path lengths and
then toggle between them. LICO® 100 uses the corresponding set of calibration data automatically.
C1 Calibration
LICO® 100 features a calibration memory for 11mm round cuvettes and 50mm square cuvettes. To be
on the safe side, calibrate LICO® 100 at least every day. In the calibration, the employed medium is
assigned a transmission of 100% over the whole spectral range. Observe the following rules for
calibration:
• The cuvette type selected for calibration must be identical to the one used for measurement,
otherwise wrong Iodine, Hazen and Gardner values are given.
• Use always clean cuvettes and fresh distilled water for calibration.

Instrument calibration for color measurement
1. Turn-on instrument and printer, if desired. After self-check and
zero measurement, LICO® 100 might ask for calibration. If
LICO® 100 is already on, make sure the cuvette compartment is
empty and press the blue CAL - key. The display reads:
2. Fill a clean cuvette (material and path length to suit your
samples) with distilled water and put it into the measuring
compartment.
3. LICO® 100 detects the cuvette type automatically.
4. Now press the blue CAL - key again to trigger calibration.
5. When the calibration is over and the printer is on, date, time and selected cuvette type are
printed, e.g. :
Then LICO® 100 prompts „Please insert sample cuvette“. Now you can insert your sample cuvette
directly. As soon as you have done so, LICO starts measuring automatically. To calibrate one more
path length, remove the cuvette and press the blue CAL -key again.
Please calibrate carefully to avoid mismeasurements caused
by faulty calibration.

C3 Iodine Number
DIN 6162 defines the Iodine color number as mg of iodine per 100ml of potassium iodide solution.
Color matching by the Iodine number serves to judge the shade depth of clear liquids like e.g. tensides,
plasticizers, resins, oils and fatty acids, whose colors resemble that of an equally layered solution of
potassium iodide. For Iodine numbers less than or about 1, the Hazen number according to DIN-ISO
6271 should be preferred.3 Sampling and preparation are described in chapter B6. A satisfactory
precision of the Iodine value is achieved with a 11mm round glass cuvette.
Measuring procedure
1. Fill the sample liquid into a cuvette and insert it into the
corresponding compartment. Measurement starts auto-
matically.
2. After the measurement, the color value is indicated on the
display.
3. Now press the } -key (DIM) until the Iodine number appears on the display.
C4 Hazen Color Number (APHA-Method)
The Hazen color number (DIN-ISO 6271, also known as "APHA-Method” or “Platinum-Cobalt-scale”)
is defined as mg of platinum per 1L of solution. The Hazen parent solution is composed of 1.246g
potassium-hexachloroplatinate (IV) and 1.00g cobaltous (II)-chloride dissolved in 100ml of hydrochloric
acid and filled up with distilled water until reaching 1000ml. The Hazen color scale serves to determine
the colors of nearly water-clear products. It has a narrower gradation in the light yellow range than the
Iodine scale and reaches even water-clear casts.
Attention:
Samples with Hazen values between 50 and 1000 can be measured with sufficient
accuracy in 11mm round cuvettes.
Hazen values < 50 should be mesured in 50mm cuvettes,
Hazen values < 10 should be measured with the cuvette which was used for
calibration, because nearly water-clear products are susceptible to giving faulty measuring
results due to cuvette tolerances.

C5 Gardner Color Number
The Gardner color number is defined in DIN ISO 4630. The lighter Gardner color standards (1 to 8)
are based on potassium-chloroplatinate solutions, color numbers 9 to 18 on ferric(III)-chloride,
cobaltous(II)-chloride and hydrochloric acid solutions. LICO® 100 determines the Gardner number at
all cuvette path lengths (in 50mm cuvettes only values between 0 and 4), with 11mm cuvettes providing
sufficient accuracy.

C6 Mineral Oil Color Number ASTM D 1500 And ISO 2049
The Mineral Oil Color Scale is used for matching the colors of mineral oil products like lubricating oil,
fuel oil, diesel oil and paraffins. The color scale begins at 0 for water-clear, colorless oils and ends at
8 for very dark brown oils. Visual matching is in steps of 0.5 (0.5 1.0 1.5...). LICO® displays the results
in steps of 0.1. For samples of stronger hue than color glass 8,
color value D8 is displayed.
GG Owing to the intensive color gradation of the ASTM4 D 1500 color
number, this is only determined for the 11mm round cuvette. There
is no determination of path length 50mm.
Measuring procedure
1. Fill the sample liquid into a cuvette and insert it into the
corresponding compartment.
2. After the measurement, the color value is indicated on the
display.
3. Now press the } -key (DIM) until the ASTM- number
appears on the display.
C7 Saybolt Color Number (ASTM D 156)
The Saybolt color scale is used to match colors of refined oil products like fuel and kerosene or also
petroleum waxes and pharmaceutical white oils. Its colorimetric characteristics are comparable with
those of the Hazen scale (APHA). The Saybolt scale begins at +30 (brightest coloration,
corresponding to approx. 8-10 Hazen) and ends at -16 (stongest coloration, corresponding to approx.
350 Hazen).
FF Measurements can be made with cuvettes of 11mm or 50mm path lengths. The greater the path
length, the better the measuring accuracy (50mm recommended).

D3 Maintenance and Test Media ControlEven a perfected product like LICO® 100 from Koehler requires careful handling. Use a dry cloth or a
mild household cleaner for the housing, but never solvents like naphta, acetone or the like. The optical
elements should be cleaned by our maintenance staff.
A certified set of test solutions is available for test media control according to ISO 9000.
The test set comprises six bottles
containing 50ml of test solution each, a
quality control certificate according to DIN
55350 part 18, 4.1.2 and a test protocol
for the documentation of reference, actual
and tolerance values.
LICO® 100 is tested as described in
enclosed test instruction. The instrument
should be tested in regular intervals of 1 to
2 weeks, depending on its application and
frequency of use.

D5 Lamp ExchangeThe lamp compartment is left of the display and covered with a slotted cap on the upper side of the
housing. If the lamp is broken, it should be exchanged by Koehler service staff, because we
recommend a general instrument check-up after an operating period of 1-2 years. If you insist on
doing it yourself, proceed as follows:
R e m o v e p o w e r s u p p l y u n i t o r b a t t e r y!
Remove the grey cover of the bit-box. Loosen the
fixture of the bit-box by pushing the locking clamp ��
and put it apart. Unplug contact �� from the lamp.
Loosen the metal clamps �� at the upper end one
be one from their stay and hinge them away. Take
the lamp �� off and put in a new one with the
marking pointing to the left.
Attention: Do not touch the glass bulb of the
lamp.
Hinge the metal clamps back to their places and fix
them to their stay. Connect the new lamp with the
plug-in contact �� and do the same steps as for
dismantling, but in reverse sense. Only when the
instrument is mounted completely, turn it on and test
it.

D6 Program-Module Card (BIT-BOX) of LICO® 100
The program module card (BIT-BOX) permits fast and comfortable updating of the internal software
and an easy extension of color systems. The slot for the program module card is at the rear side of
the housing. The instrument must be off when the bit box installed. Program updates or extensions are
made by inserting the bit box first and then turning the instrument on. Follow the display prompts. Turn
the instrument off after updating and remove the bit-box again. For color number extension, the bit-box
can be used but once.
