The most popular line of rotational rheometers from the World 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 Discovery Hybrid Rheometer is available in three models to meet your specific needs of sensitivity and capability. From the world’s most sensitive rotational rheometer – the HR-3 – to the general-purpose HR-1, every Discovery Hybrid Rheometer is built on a common core of the TA Instruments advanced drag cup motor and second generation magnetic thrust bearing. Find out how the Discovery Hybrid Rheometer will improve your rheological characterization by making better measurements over a wider range of conditions with less time in the laboratory.
