Abstract: A viscosimeter of the kind wherein a capillary tube containing a fluid, the viscosity of which is to be measured, and a metal ball is supported so that the ball will gravitate from the top of the tube to the bottom and a magnet is used to periodically raise the ball in the capillary and release it. The viscosity is determined by the rate of descent of the ball in the capillary tube.
