Measure and analyze the rheological properties of a wide range of different samples. Increase efficiency and minimize the risk of operator errors.
With the Thermo Scientific™ HAAKE™ Viscotester iQ Rheometer we provide an intelligent solution for your daily rheological challenges. Designed for intuitive operation, the HAAKE Viscotester iQ Rheometer adapts to individual measurement requirements in laboratories focused on quality control.
This HAAKE Viscotester iQ Rheometer sets new standards in modularity, ease of use and intelligent user guidance. It is the instrument of choice for simple viscosity determination as well as for complex rheological investigations from low viscous liquids to stiff pastes and semi-solids. Used as a standalone unit or fully software controlled, its compact size and small footprint makes the Viscotester iQ Rheometer a portable unit for mobile use or a major tool in quality control laboratories.
The development of the next generation Viscotester was driven by the demands of new rheological tasks in quality control. We combine decades of experience in rheology with solutions designed for highly dynamic working environments. Our goal is to enable fast, reliable and precise rheological measurements with maximum ease of operation.
