Brookfield Engineering, Middleboro, Mass., offers new Rheo3000 V.2 software for use with its new family of RST touchscreen rheometers. The new software offers quick and easy measurements—from single-point viscosity for QC to complete flow-curve analysis for R&D. All the operator has to do is enter the shear stress or shear rate, temperature, and test time requirements, and the instrument completes the data collection and analysis.
The unit can perform a wide variety of tests: viscoelastic modulus, yield stress, viscosity vs. shear rate profile, thixotropy calculation, creep behavior, recovery after flow, and temperature sensisitivity. QC Mode allows tolerance bands to be placed around measurement data for immediate visual pass/fail determination. Mathematical data-processing models include
Newton, Bingham, Casson, Herschel-Bulkley, Ostwald, and Steiger-Ory.
