To measure viscosity at a controlled shear rate, at a controlled shear stress or to make a direct yield stress measurement, Brookfield has a Rheometer to meet your need.

Available models

Brookfield Rheometers PVS

The Brookfield PVS is a coaxial cylinder, controlled shear rate rheometer used in applications under pressure at temperatures where sample boil-off is a problem.

The PVS is a dynamic coaxial cylinder, controlled shear rate rheometer allowing quick and easy viscosity measurements under pressure at temperatures where sample boil-off is a problem.

The PVS can be used to simulate process conditions for small fluid samples in a laboratory benchtop environment. Applications include chemical compounds containing volatile materials, oil industry, drilling muds and fracturing fluids, processed foods, polymers and paints. Any test sample requiring absolute viscosity measurement under totally enclosed conditions is a viable candidate.
