Krebs Unit Viscometer Model KU-2

 

A completely digital calculating Krebs Unit Instrument with all the reliability you'd expect...now with relative centipoise display.

  • Continuous sensing and display in Krebs units, grams, and centipoise.
  • Magnetic coupling for rapid spindle attachment and easy removal, providing time savings of 5 to 10 seconds per test.
  • Allows rapid sample measurement to determine required consistency.
  • LED Digital Display of: Krebs Units (increased resolution in 0.1 KU increments), Grams (in 1 gm increments) and Centipoise (cP).
  • Base accommodates standard pint, 1/2 pint, and quart cans.
  • The optional paste spindle is suitable for use with high consistency materials such as roller mill pastes.
  • NIST traceable viscosity standards available.
  • Protective rubber boot covers the lab stand rod, eliminating potential problems with up/down viscometer head movement during viscosity tests.
  • Universal power supply located externally to the viscometer head which eliminates potential electrical damage due to variable line voltage.
  • Single piece can adapter to accommodate pint and half-pint cans.
  • Instrument display has slightly larger alpha numeric characters. Scientific units for KU, grams, cP appear on the display.

How it Works

top

Samples are tested in standard paint industry cans held by a fixture located on the viscometer base. The can is filled to within 3/4" (20mm) of the top. The KU-3 operating lever has two positions:

Up: Spindle stationary, drive motor off
Down: Spindle rotating; sample being measured

The displayed reading can be held by depressing the HOLD switch at any time. With the viscometer in the HOLD configuration, the display may be switched to compare the Krebs unit (KU) reading with the associated gram (gm) reading, and centipoise. Brookfield Oil Viscosity Standards in Krebs units are NIST traceable and are recommended for verifying calibration of the KU-3 Viscometer.

Annual Calibration Service is Recommended - We recommend that this instrument be returned on an annual basis. Having this annual maintenance done will ensure the instrument's long life and optimal performance.

The air-purge option is not available in the Model KU-3.

Please note:

  • The cP reading from the KU-3 will not necessarily agree with cP values
    measured with other instrumentation due to:
    1. Unique shear rate of the KU-3 paddle spindle.
    2. Uniqueness of the Krebs unit scale. (The centipoise value should not be used for purposes of calibration.)
  • Use only Brookfield KU mineral oils for calibration check.
  • The cP readings will only be valid when using the paddle spindle.
  • The paste spindle may not be used to determine cP.

 

Conversion Between Stormer Viscometer Krebs Units and Viscosity Cup Drain Time

top


The three reduced size charts, at left. are only for illustrating this conversion method. Ask for complimentary full size (8-1/2" x 11") Krebs Units Conversion Charts and latest Krebs Stormer literature.

Three Step Conversion Procedure

Step 1: Knowing the Krebs value, convert this value to Centipoise viscosity. On the attached Krebs Units to Centipoise conversion chart, read vertically from the known Krebs unit to the curve and then horizontally to the left to the Centipoise value. Record this value.

Step 2: Convert the Centipoise value for the test material in question to Centistokes. On the attached Centipoise - Centistoke conversion chart, locate the Centipoise value from Step 1 on the vertical scale.Read horizontally to the right from this value to the Weight Per Gallon or Specific Gravity line, estimating values between lines, applicable to the test material in question. From this intersection read directly downward to the horizontal Centistoke scale and record this value.

Step 3: Determine the drain time in seconds for the viscosity cup in question from the Centistoke value from Step 2. For this conversion, refer to the Gardco Viscosity Cup Equivalent Chart or the conversion chart furnished with each Gardco produced viscosity cup. Only viscosity cups accommodating the highest range of viscosity are satisfactory for this conversion as most Krebs measurements are in the range from 500 to 1400 Centistokes.

For satisfactory results, do no use a viscosity cup above its recommended top limit. This conversion is accurate only for Newtonian or near Newtonian materials. Viscosity of materials that deviate greatly from these true liquids may not be “seen” the same by the Stormer and viscosity cup methods of measurement.

Please refer to the appropriate cup conversion chart. If you do not have one please contact us at 1-800-762-2478 or 954-946-9454.
