rheometer

A rheometer is a scientific instrument used to measure how a material flows and deforms under applied forces, essentially assessing its thickness (viscosity) and elastic properties (like a soft solid). It works by applying controlled stress or strain to a sample—such as liquids, gels, or pastes—and recording the response. This helps scientists and engineers understand a material’s behavior under different conditions, which is important for product development, quality control, and research across industries like food, pharmaceuticals, and materials science.
