Company History

About Us

For over 80 years, Brookfield Viscometers and Rheometers have been considered the world leader in laborory and online viscosity 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.


In the summer of 1932, at age 21 and while completing his studies at MIT (Massachusetts Institute of Technology), Don Brookfield, Sr. told his father "I can build a better one". He was referring to the viscometer he and his father, Gordon W. Brookfield, Sr. considered buying when looking for one to use in the manufacture of synthetic resins to measure the fluid's physical characteristics. Don sold his first working dial reading viscometer in 1934, and later with his father and brothers, incorporated the business and launched the Dial Reading Synchro-electric Viscometer, the product that would become the standard throughout the world.

Brookfield Engineering continued to build and expand, opening offices in Germany, the United Kingdom and China. Brookfield branched into other measurement disciplines such as texture analysis in 2003 and powder flow testing in 2010, allowing expansion into an even broader range of applications in industries such as food production, inks, paints, coatings, solvents, adhesives, petroleum products, plastics, health, cosmetics, and packaging.

In 2016, Brookfield Engineering was acquired by AMETEK, a leading global manufacturer of electronic instruments and electromechanical devices. Now known as AMETEK Brookfield, the company continues the manufacturing of its well known line of viscometers, rheometers, texture analyzers and powder flow testers from its main headquarters in Middleboro, MA USA.
