An Improved Shear Stress Calibration Method for the Haake Rotovisko

Abstract

Two shear stress calibration methods for the Haake Rotovisko Model RV1 were tested for non‐Newtonian shear‐thinning fluids. Determination of a shear stress calibration constant for each shear rate provided a significant improvement over the manufacturer's calibration method when both methods were compared with corresponding data generated with the Weissenberg Rheogoniometer.
