Rheometer: MCR 102, 302, 502

The new MCR rheometers are based on a concept at the cutting edge of technology. The EC motor technique, the low friction bearing and the normal force sensor have been optimized over years to satisfy the highest demands of rheologists. Any type or combination of rheological tests, both in rotational and oscillatory mode, are possible with the MCR rheometers. The modularity of the system allows the integration of a wide range of temperature devices and application-specific accessories. The innovative and patented features Toolmaster™TruGap™ as well as T-Ready™ are breakthroughs in terms of user-friendliness. TruRate™ and TruStrain™ ensure absolute control at any time during rheological tests
