Falling Ball Viscometer KF10

The Falling Ball Viscometer KF10 is based on the measuring principle by Hoeppler. It enables simple but precise measurements of the dynamic viscosity of light-transmissive Newtonian liquids. It is preferably used in research, in processing control and in quality control.

For the measurement of low viscosities and for the control of pseudoplastic behavior the measuring range (DIN 53015) is extended by optional adjustment of the operation angle.

A special glass ball is added for measuring the viscosity of gases an vapours.
