Saint Clair Systems, Inc. Norcross Cup

The Norcross Cup is an efflux test cup designed for manually measuring the viscosity of hotter, thicker fluids than conventional Zahn or Shell cups. Featuring internal timing pins, a user simply dips the cup into any fluid up to 50,000 cps, regardless or temperature, and then measures the time it takes for the fluid to drain from pin to pin, rather than from the bottom.Measuring laminar flow instead of the turbulent of transitional flow out the cup's bottom, the Norcross Cup is available with several different hole sizes to correspond with various viscosity ranges. Suitable for use with hot fluids, it is made of brass and stainless steel, and has a brass chain to permit measurements in awkward positions under pipes and equipment.
