Blade-type rotor viscoMeter

The blade-type rotor viscometer drives a blade to rotate in the sample via a motor, measuring the viscous resistance experienced by the blade to calculate viscosity. It is used to determine the flow characteristics of non-Newtonian fluids such as coatings and inks, and in the printing and paper industries to control the application performance of slurries and coating liquids.
Selection
When selecting, consider matching the rotor size to the sample characteristics, using a small rotor for high-viscosity materials. Choose a torque sensor based on the measurement range, and opt for stainless steel for corrosive materials. Ensure that the temperature control accessories are consistent with the sample testing conditions, and verify that the calibration certificates meet industry standard requirements.
