Brookfield viscosity refers to the viscosity measurement obtained using a Brookfield Digital Viscometer, a widely recognized rotational viscometer used across industries. The instrument operates by rotating a spindle at a defined speed (RPM) or shear rate while immersed in the sample. The resistance encountered by the spindle during rotation is measured and converted into a viscosity value.

Different spindle designs are available to suit various sample types and testing requirements, making the Brookfield Digital Viscometer ideal for measuring the viscosity of paints, coatings, adhesives, polymers, food products, pharmaceuticals, and other liquids or semi-solids. It ensures accurate, repeatable, and reliable viscosity analysis for quality control and research applications.
