ABSTRACT:
A rotational viscometer instrument of the type having a rotor driven to rotate about an axis, the rotor for contact with a fluid, the viscosity or related property of which can be measured by measuring torque or drag on the rotor rotating in contact with the fluid through a torque or drag measuring element, is improved by a means for interjecting a predetermined calibration factor into the instrument based on a viscosity of a fluid of known viscosity and the rotor and the torque or drag measuring element such that the true viscosity sensing ability of the instrument is enhanced.
