Coaxial RheoMeter

The coaxial rheometer measures the relationship between torque and rotational speed of a sample under shear by rotating the inner and outer cylinders relative to each other, obtaining rheological parameters such as viscosity and modulus. It is used to analyze the characteristics of fluids like coatings and inks during flow and deformation, guiding formula adjustments and process control.
