RheocalcT Software allows the operator to automate viscosity testing from a PC when using the DV3T Touch Screen Rheometer and the DV2T Touch Screen Viscometer. The user interface for RheocalcT has a range of choices for test method creation and data gathering/analysis. Loop functions allow performance of repetitive tasks on test samples that require viscosity measurement at multiple rotational speeds, different temperature set points, and discreet time intervals. Viscosity data averaging is possible for individual tasks within a test step or over multiple steps in the total test program. Advanced data analysis to assess yield stress and pseudo plastic index can be performed with a choice of math models: Bingham, Casson, NCA/CMA Casson, Power Law, IPC Paste, and Herschel-Bulkley.
