Rotational Viscometer / Rotary Viscometers

Rotational viscometers are designed to measure viscosity by analyzing the torque required to rotate a spindle submerged in a fluid at a constant speed. The continuous rotation of the spindle ensures calculations are made over time, allowing time-dependent fluid analysis. Digital models can evaluate low, medium, and high viscosity materials. Considerations for rotational viscometers should include the level of viscosity application, speed, and spindle configuration. Each consideration configuration will help hone the sensitivity and accuracy of measurement for your specific application. Additional considerations would be unit size and dimensions.
