Measuring Viscosity and Yield Stress

The DV3T rheometer available from Brookfield Engineering features a 7” full color touch screen that easily shows all test parameters together with measured values for temperature, viscosity and yield stress. The DV3T provides fast, simple, single point viscosity, making it a multi-purpose instrument for demanding R&D departments and QC labs that perform detailed flow behavior.

In addition, on screen graphing displays real-time test information, which can be recorded by users on a printer or sent to a computer. Integrated math models like Power Law offers quick data analysis for flow index and other variables.
