Description

Advanced Software

LAB KARS (“Kayeness Advanced Rheology Software”) is the most powerful and user-friendly rheological software package for Windows™. Its easy-to-use features include Bagley and Rabinowitsch corrections as well as Power Law, Carreau, Modified Cross, and polynomial viscosity models. This software allows users to merge multiple datasets from shear stress, shear rate, or thermos-stability tests. The integrated KARS SQC module can be used to quickly identify viscosity variations across different material batches. A program for correlating melt viscosity with intrinsic viscosity, for PET and Nylon, is also included.

Real-Time Display

In addition to all its other powerful features, LAB KARS for Windows™ offers a real-time display of force or pressure versus time as a test progresses. This feature allows the operator to recognize the steady-state flow behavior of the material. Additionally, contaminants, unmelted resin, or bubbles in the material can be identified by spikes in the force-vs-time curve.
