Rheometer
From Wikipedia, the free encyclopedia
Rheometers are viscometers which are able to measure visco-elastic properties of materials rather than viscosity alone.
A rheometer is a kind of viscometer that measures visco-elastic properties of materials beyond just viscosity. Rheology is the flow of fluids and deformation of solids under various kinds of stress and strain. A rheometer, therefore, measures material behavior such as yield stress, kinetic properties, complex viscosity, modulus, creep, and recovery. Most rheometer models belong to three specific categories. These are the rotational rheometer, the capillary rheometer, and the extensional rheometer. The most commonly used of these is the rotational rheometer, which is also called a stress/strain rheometer, followed by the capillary rheometer
