Abstract
An improved viscosity measurement device which employs a sample container having a sleeve therein and a rotor disposed within the sleeve. The rotor is cylindrical and includes openings which extend through the rotor in the axial or longitudinal direction, parallel to the rotor axis. This enables the viscometer to test non-Newtonian oils at very low shear rates without introducing non-uniform shear rate.
