The Brookeld 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.

Please check to be sure that you have received all components, and that there is no damage. If

you are missing any parts, please notify Brookeld or your local Brookeld agent immediately.

Any shipping damage must be reported to the carrier.

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.
