The latest technological breakthroughs from the world’s leader in Rheology.

The new Discovery Series Hybrid Rheometer (DHR) represents the latest technological breakthroughs from the world leader in rheology. It 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-1 is a rugged, accurate, field-proven rheometer. The HR-1 shares the cutting-edge technology of the Discovery Hybrid Rheometer family in a platform that is ideal for production control, asphalt manufacture, and a wide range of general measurements of viscosity and viscoelasticity.

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.

The HR-3 is the pinnacle of the Discovery Hybrid Rheometer family. Featuring the world’s best available torque sensitivity and the all new patent-pending Optical Encoder Dual Reader, the HR-3 is the most advanced single-head rheometer in the world.
