Bkfld-Eng-int-main-lobbyBrookfield Engineering Laboratories has long been considered the World Standard in Viscosity Measurement and Control. From the original Synchro-electric Viscometer to today's sophisticated DV-III Ultra Rheometer, the Brookfield name is synonymous with quality, dependability and reliability. In recent years, we have added the addition of texture analysis equipment to our line of products. This axial testing capability enhances Brookfield's existing product line by providing more flexibility in solving the rheological and texture measurement needs of our customers.

For over 80 years Brookfield Engineering Laboratories has been the world's leading manufacturer of Viscometers and Rheometers for laboratory and on-line process control applications. The reputation of the Brookfield viscometer is built on more than just a superior scientific principle. When you use a Brookfield, you are joining thousands of people who have made it a World Standard of viscosity measurement. There are more Brookfield viscometers used in industries worldwide than any other viscometer. Your associates, suppliers or customers probably own a Brookfield. Many Society and Industrial specifications describe the use of a Brookfield viscometer. Laboratory Viscometers and Rheometers include Dial Reading (Analog) and Digital Display Model of which several are Programmable. On-line Process Control Viscometers include Probe, In-Tank, In-Line and flow through models.

All Brookfield viscometers employ the well-known principle of rotational viscometry; they measure viscosity by sensing the torque required to rotate a spindle at constant speed while immersed in a fluid. The torque is proportional to the viscous drag on the immersed spindle, and thus to the viscosity of the fluid.

Viscosity Standards

Brookfield Viscosity Standards provide a convenient, reliable way to verify the calibration of your Brookfield Laboratory Viscometer/Rheometer. Brookfield Viscosity Standards are

Silicone Viscosity Standards

  • 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

Newtonian, and they are available as either silicone or oil. Silicone fluids are less temperature sensitive than oil fluids.

Note: Brookfield recommends that all fluids be replaced annually
