These fluids are most commonly used to verify calibration of Brookfield Viscometers/Rheometers.

• Accuracy: ±1% of viscosity value

• Excellent temperature stability

• Recommended for use with Brookfield and most other rotational viscometers

• Most economical

• Special viscosity values and temperature calibrations available upon request

These fluids are used for specific instruments using cone/plate or Krebs spindle geometry. Also, certain industries may require use of oil standards.

• Accuracy: ±1% of viscosity value

• Appropriate for use at shear rates greater than 500 sec-1

• Recommended for use with cone/plate Viscometers at viscosities above 5,000 cP

• Recommended for Brookfield CAP series and KU-2 Viscometers and R/S Rheometers

• Brookfield oil viscosity standards are hydro-carbon based, either mineral oil or polybutenes

For viscosity selection, please refer to the table at right.

For calibrating CAP Series cones - each spindle has its own fluid

How to select a CAP fluid (refer to the chart at right):

• Determine which viscometer is being used: High Torque or Low Torque
• Determine which temperature model is being used: Low Temperature (5°C-75°C) or High Temperature (50°C-235°C)
• Determine which cone is being used.

For viscosity selection, please refer to the table at right.

 
For our customers needing a nonstandard viscosity or temperature range, our silicone fluids can be modified to meet most requirements.
