Rheometers measure the rheological properties of materials, how they flow and deform in relation to applied force.
Rheometers have wider capabilities than viscometers, which are limited to measuring the viscosity of fluids under certain conditions. A rheometer, on the other hand, can measure both viscosity and elasticity under a wide range of conditions.
There are various types of rheometer:
• Dynamic rotational
They are ideal for testing complex types of non-Newtonian fluids, including plastics and pseudoplastics.
They have a broad range of industrial and quality control applications, testing materials such as paints and inks, cosmetics, pharmaceuticals, oil and petroleum, and food and drink.
The latest Rheometers from SciMed and our partners.
One instrument covers a wide viscosity range (0.1 – 60,000,000 cPs) and has 6 different measuring geometries including standard spindles and cone and plate, Peltier or water bath temperature control, stand alone or software control, plus a small footprint.
The highly flexible Modular Advanced Rheometer System (MARS) provides accurate results, easy handling, and application-driven solutions for material characterisation.
Thermo Scientific™ HAAKE™ MARS™ iQ Rotational Rheometers offer reliable, intuitive and flexible rheological measurements. The iQ rheometer is designed for the QC laboratory to provide fast and reliable results.
