Elcometer Rotational and Krebs Viscometers

Rotational and Krebs viscometers are used to determine the viscosity of liquids which do not depend solely on temperature or pressure.


Rotational and Krebs viscometers consist of two parts - the head unit with a motor and a spindle that is driven by the motor. The viscosity is determined by measuring the resistance of the spindle as it rotates in the sample.

Rotational and Krebs viscometers gather data on a material's viscosity behaviour under different conditions and are used to measure the viscosity of non-Newtonian fluids which change viscosity when a force is applied.
