A rotational rheometer is one of the instruments used to study and measure the rheological properties of materials. It applies forced steady-state rate load, steady-state stress load, dynamic sinusoidal periodic strain load, or dynamic sinusoidal periodic stress load to the sample to observe the response data of the sample to the applied load; By measuring rheological data such as shear rate and shear stress, it is a widely used rheological measuring instrument in the field of materials, which can study the flow and deformation characteristics of samples from low viscosity fluids to high-strength solids.
