The Zahn viscosimeter is a bullet-shaped, corrosion-resistant, stainless steel cup with a precision drilled orifice. Five sizes are available for use on very thin oils to extremely heavy mixtures (20-1200 Centipoise). Viscosity is determined by the time required for a definite volume of liquid to flow through the orifice. These easy-to-use products were originally manufactured by G.E. and are still Made in USA.
