ABSTRACT:
In a rotary viscometer comprising a variable speed drive motor including a speed indicator, such as a tachogenerator or a similar device, and a measuring shaft driven by an output shaft of a rotor of said motor and carrying a measuring member immersible in a medium of which the viscosity is to be measured, the motor stator is rotatably displaceable against the action of a spring, the displacement being a measure of the viscosity. The driving connection between said motor and measuring shaft comprises at least one pair of exchangeable gears or toothed belts and said spring is exchangeable for one having a different spring characteristic.
