The DV-III Ultra combines the features of the DV-III+ Rheometer with the yield stress measurement capability of the company's YR-1 Yield Test Rheometer. In stand-alone mode, the operator enters test parameters and temperature-control requirements, and starts the program. Results are displayed on the built-in display. It also provides built-in math models for data analysis. Optional software allows the operator to control all aspects of rheological testing directly from their computer. Call 800/628.8139.
