The Discovery Series Hybrid Rheometer (DHR) combines a patented advanced drag cup motor, a second generation magnetic bearing, force rebalance transducer (FRT), and the new patent-pending True Position Sensor (TPS) in a single-head Hybrid rheometer. The DHR has unprecedented performance specification and delivers unsurpassed direct strain control, direct stress control, and normal force measurement accuracy. The DHR features all popular TA innovations including patented Smart SwapTM geometries and the widest range of Smart Swap temperature systems and accessories commercially available. The result is the most advanced, versatile rheometer platform imaginable.
The HR-2 is an outstanding general-purpose rheometer for a wide range of analytical, research, and production uses. With performance characteristics suitable for the most demanding measurements and a proven track record of reliability, the HR-2 is at home anywhere a rheometer is needed, from around-the-clock production control to cutting-edge research.
