DHR2 Rheometer (DHR)

Discovery Hybrid Rheometer 2 (DHR-2) is an advanced rotational rheometer with a combined motor and transducer (CMT) design. It has a patented drag-cup motor, the second generation of magnetic bearing, a force-rebalance transducer (FRT) for normal force control, and a true position sensor (TPS) combined in a single-head hybrid rheometer. It is a powerful tool for characterizing the flow properties of liquids and the mechanical properties of soft solids such as gels.
