Programmable Rheometers

Rotational viscometers are generally used to measure the viscosity (also referred to as apparent viscosity) of Newtonian or non-Newtonian fluids at specific rotational speeds and with specific rotors. In the polymer materials industry, such as coatings, inks, and adhesives, almost all resins, emulsions, and finished products are non-Newtonian fluids, exhibiting different rheological properties at different shear rates (which are related to rotational speed and rotor geometry).
