Abstract
A combination viscosity measuring device and stirrer has a handle portion and a shank portion, the shank portion having one or more apertures therein, the aperture or apertures being dimensioned so as to provide open span gradations. When the shank portion is dipped into and removed from a liquid whose viscosity is to be measured, the liquid will by surface tension form a film spanning one or more of the span gradations. The largest span gradation spanned by the liquid is a measurement of the viscosity of the liquid. The gradations are identified by designations so that a determination can be made as to whether the liquid has the proper viscosity for a particular application. In one embodiment the gradations may be in the form of a series of holes of different diameters, and in another embodiment the gradations may be in the form of a tapered slot.
