The Brookeld KU-2 Viscometer measures uid viscosity in Krebs units. A paddle type spindle
is driven at 200 rpm by a constant speed motor. The reaction torque of the spindle rotating at
200 rpm is converted to viscosity in Krebs Units. The digital display of the Viscometer shows
viscosity in Krebs Units (KU), the associated grams value (gm), and viscosity in centipoise (cP).
The value for centipoise is a conversion from the Krebs value as described in the ASTM standard
D562. The Viscometer will measure viscosity from 40 KU to 141 KU, at weights of 32 to 1,099
grams (the equivalent centipoise range is 27 - 5,274 cP). Application reference information can
be found in ASTM D562.

I.2 Options
Air Purge Fitting
I.2.1 Air Purge
The air purge option, Part No. KU-2A (Figure 2),
allows the interior of the KU-2 to be pressurized
with air (or an inert gas) when the instrument is
to be used in a hazardous environment. A builtin pressure switch turns the instrument off when
the pressure drops below 2.0 PSI (falling). The
switch comes on at 10.0 PSI (rising).
Connect a regulated clean air (or inert gas) sup-
ply which is non-corrosive to brass to the tting
shown in Figure 2. Adjust the pressure to ap-
proximately 25 PSI.
Note: The pressure switch range is 0-40 PSI.
DO NOT CONNECT PRESSURE HIGHER
THAN 40 PSI TO THE SWITCH!
I.2.2 Optinal Paste Spindle
The paste spindle, Part No. KU1-75Y (Figure 3), is a special
spindle; it is not included in a standard shipment/order. The
design consists of offset rod-type vanes, approximately 2 mm
diameter x 19 mm long. This spindle is suitable for use with
high consistency materials such as roller mill pastes. Do not
use this spindle to report normal Krebs Unit measurements
or centipoise. Record the grams value shown in the digital
display and note that the paste spindle was used to make the
viscosity measurement.

Refer to the manual for specic warning or caution information to avoid personal
injury or damage to the instrument.
Precautions
If this instrument is used in a manner not specied by the manufacturer, the protection
provided by the instrument may be impaired.
This instrument is not intended for use in a potentially hazardous environment.
In case of emergency, turn off the instrument and then disconnect the electrical cord
from the wall outlet
The user should ensure that the substances placed under test do not release poisonous,
toxic or ammable gases at the temperatures to which they are subjected to during the
testing.
I.7 Printer Connection
The KU-2 is equipped with a parallel printer port located on the side of the instrument allowing
printing with a parallel printer. A standard parallel printer cable (25 pin, Type D Centronics, available from Brookeld as part number CAP-86) is
used to connect the viscometer to the printer.
When connected to a printer, the KU-2 will print
one line of data each time the "Hold Reading"
switch is moved to the down position.
The data line includes the viscosity (in Krebs
Units and centipoise) and the associated weight
(in grams):

I.8 Viscosity Units
The Krebs Unit is a special measure of viscosity that is not based on the Newtonian model of
ow. The ASTM test method D562 was originally developed around the special conditions of an
instrument that used gravity to drive a paddle spindle at 200 rpm. The weight required to achieve
200 rpm varied depending upon the viscosity of the uid under test. The Krebs unit was developed through the correlation of the weights used and the time required for 100 revolutions of the
paddle. The ASTM standard also provided a correlation from Krebs Units to the scientic measure
of viscosity in centipoise.
The Grams scale represents the weight required to drive the paddle through the test uid at a rate
of 200 rpm. The gravity drive system specied in ASTM D562 required that the weight be varied
until 100 revolutions were achieved in 30 seconds (200 rpm). The KU-2 drives the unit at 200 rpm
automatically and provides the grams value that would be required on the gravity drive system.
The grams scale is not a viscosity unit.
The Centipoise scale is available through a correlation originally dened in the ASTM test method.
Since this value is based on the Krebs Unit, it is not equivalent to centipoise values determined using
other types of viscometers, such as the Brookeld RVDV-I+. The centipoise values displayed on
the KU-2 are for reference only. Comparisons to measured values from other instruments should
not be made.
I.9 Cleaning
Make sure the instrument is in a decent working environment (dust-free, moderate
temperature, low humidity, etc.).
Make sure the instrument is on a level surface.
Hands/ngers must be clean and free of residue sample. Not doing so may result in
deposit build up on the upper part of the shaft and cause interference between the shaft
and the pivot cup.
Be sure to remove the spindle from the instrument prior to cleaning. Note left-handed
thread. Severe instrument damage may result if the spindle is cleaned in place.
Instrument and Keypad: Clean with a dry, non-abrasive cloth. Do not use solvents
or cleaners.
Immersed Components (spindles): Spindles are made of stainless steel. Clean with a non-
abrasive cloth and solvent appropriate for sample material.
When cleaning, do not apply excessive force, which may result in bending spindles.

Note: Do not remove the thumb screw. If dropped, it may fall into the sample.
II.3 Troubleshooting
If the operating handle is in the DOWN position and the display locks up and/or the spindle does
not rotate the following should be checked:
• Be sure the HOLD switch is in the UP position. If the hold switch was in the DOWN position
prior to engaging the operating handle, dashes (——) or the previous reading may appear in
the display.
• The KU-2 requires a shutdown (power off) period of at least 30 seconds before it can be operated
properly. If the unit had previously been turned off and immediately turned back on (without
a 30 second shutdown period) both the display and rotation may temporarily lock up.
If you experience these problems, simply raise the operating handle, turn the unit off and wait a
minimum of 30 seconds before turning the power back on.

Appendix A - KU-2 Calibration Information
The accuracy of the KU-2 is veried using viscosity standard uids calibrated in Krebs Units, which
are available from Brookeld Engineering Laboratories or your local Brookeld dealer/distributor/
representative. Note: Calibration should not be veried using the centipoise scale. The centipoise
scale is for reference use only and is based on a correlation from the Krebs Unit details in the ASTM
test method D562. Viscosity Standards are calibrated at 25°C. Available standards are listed in
Table A-1 below:
Table A-1
Brookeld Viscosity Standard Nominal Viscosity (KU) Temperature (°C)
KU61 61 25
KU73 73 25
KU87 87 25
KU99 99 25
KU106 106 25
Brookeld Viscosity Standards
We recommend that Brookeld Viscosity Standard Fluids be replaced on an annual basis, one year
from the date of initial use. These uids can be stored under normal laboratory conditions. Disposal
should be in accordance with local, state and federal regulations. Material Safety Data Sheets are
available on our website: www.brookeldengineering.com/support/documentation.
Calibration Check Procedure
The frequency of the calibration check should be based on your company's standard practice for test
and calibration of instruments.
1) Select any two viscosity standards listed in Table A-1 to perform your calibration check.
The viscosity standards are very temperature sensitive. The viscosity value of the uid will
change with temperature so it is important to control the temperature to 25.0°C.
Note: Do not use viscosity standards calibrated in centipoise.
2) Pour the selected uid into a standard US 1-pint can. The spindle and the uid in the can
should come to temperature equilibrium before proceeding with the calibration check.
It is important that the uid and the spindle come to 25.0°C, ± 0.1°C, before proceeding
with the calibration check.
3) Once the uid and spindle have come to thermal equilibrium, place the sample container
on the viscometer base, using the KU1-74 adapter. Switch the power switch and printer (if
used) to "ON". Switch the Hold Reading Switch to the "UP" position. Turn the Select knob
to "KU".
4) Move the viscometer handle down to the lowest position. The spindle will begin rotating
once the handle is within 1/2 inch of the lowest position.
Brookeld Engineering Labs., Inc. Page 11 Manual No. M04-242-D0612
5) Wait ve (5) seconds for the reading to stabilize. Switch the Hold Reading Switch to the
"DOWN" position. You will need to record measurements in KU and gm. These two
values work together to let you interpret the calibration results.
6) After you have recorded results in KU, then move the Selector knob to the "gm" position
and record your reading in grams. If you are using a printer, three measurements will be sent
to the printer and will print out as soon as the Hold Display switch is switched back to the
DOWN position.
Interpretation of Calibration Check Results
When verifying the calibration of the KU-2, the instrument tolerance and viscosity standard uid
tolerance must be combined to calculate the total allowable error.
The KU-2 is accurate to ± 11 grams, which is 1% of the full scale range in grams. The Brookeld
Viscosity Standard is accurate to ± 1% of the stated viscosity in KU.
The total allowable error should be stated in KU. Since the instrument accuracy is stated in grams,
you will have to use the comparison table (Table A-2) and convert from grams to KU.
Correct interpretation of your calibration results requires that you compare your readings in grams to
the equivalent in KU. You must then bracket your reading with upper and lower limits based on the
allowable error of ± 11.0 grams. Convert this acceptable range in grams (as dened by the upper and
lower limits) to KU units.
Example: Calculate the allowable error of the KU-2 using uid KU106; the stated viscosity
of the uid is 104.8 KU. The viscometer indicated a measured viscosity of 105
KU and 410 grams.
1) Measured results from the calibration check in grams were 410 grams. Locate 410 grams on
the conversion chart (Table A-2).
2) The KU-2 is accurate to ± 11.0 grams. Starting from 410 grams, count 11 places above and
below the 410 grams. This is called "bracketing" the acceptable range. In this case, the
acceptable range will be from 399 grams to 421 grams.
3) Convert the acceptable range in grams to KU. Locate the minimum and maximum grams
bracketed. Look to the right of each number for the conversion to KU. In this case, it will be
103.9 KU minimum and 105.7 KU maximum. The total difference between 103.9 and 105.7
KU is 1.8 KU. Therefore, the accuracy is ± 0.9 KU. This is the accuracy for the Viscometer
in KU, ± 0.9 KU.
Brookeld Engineering Labs., Inc. Page 12 Manual No. M04-242-D0612
4) Now that you have the accuracy for the instrument, you can add it to the accuracy of the
uid. The uid is accurate to ± 1% of the stated value in KU. The viscosity standard is
calibrated at 104.8 KU, ± 1% is equal to ± 1.0 KU.
0.9 KU (instrument accuracy)
+ 1.0 KU (uid accuracy)
1.9 KU (total allowable error)
5) Total allowable error for the calibration check in this example is 104.8 KU, ± 1.9 KU
(102.9 KU to 106.7 KU). Since the measured reading of 105 KU falls within this range, the
Viscometer is considered in calibration.
