Abstract
A highly efficient, highly accurate controllable digital viscosity testing system is provided. The system incorporates a variable speed motor, a digital encoder, a beam-deflection and/or magnetic torque resistance for unidirectional or bi-directional measurement of shear, and an API recommended practice 13B-11ISO 10414-1 bob and rotor sleeve measurement device for submerging in a test sample to measure shear forces exerted by the test sample.
