Brookfield: The DV-III™ Ultra Rheometer now features USB connectivity. It combines the features of a rheometer with the yield stress measurement capability of the YR-1 Yield Test Rheometer. In stand-alone mode, the operator enters test parameters, temperature control requirements and starts the program. The results are displayed on the built-in display. Optional Rheocalc32™ software lets operators control all aspects of rheological testing directly from a computer.
