Rheometers can be used to assess the rheological properties of materials by applying a force (stress, strain or strain rate) and measuring the resultant deformation or flow.

A rheometer can be used to measure the viscous and elastic properties of liquids, suspensions, pastes and slurries for quality control, research and development and manufacturing purposes. Whereas viscometers are capable of measuring the viscosity at a single velocity, a rheometer can be used to measure:

Rheometers can test for the following properties:

• Yield stress
• Viscoelasticity
• Extensional viscosity
• Creep compliance
• Thixotropy
• Stress relaxation

Rheometers are suitable for a wide range of samples and applications. These include:

* Food and drink
* Polymers and plastics
* Paints and inks
* Pharmaceuticals and cosmetics
* Building materials
* Petrochemicals
