Rheometer is a specialized skill that involves the measurement and analysis of the deformation and flow characteristics of materials, mainly polymers, and fluids. It requires expertise in the use of equipment such as a rheometer, which measures the viscosity, elasticity, and other properties of materials under different conditions. An understanding of rheology, the science of deformation and flow, is also essential. Rheometers are used in industries such as food processing, cosmetics, and oil exploration.
