Zion immersion Cup

The Zahn viscosity cup measures viscosity by timing the flow of liquid through a standardized orifice at the bottom of the cup. Its principle is based on the inverse relationship between the flow rate of the fluid under gravity and its viscosity. It is used for rapid viscosity testing of Newtonian fluids such as paints and inks, making it suitable for quality control in production environments.
Selection
The selection of a Zahn cup must match the viscosity range of the liquid being tested, with common cup numbers 2-8 corresponding to different orifice sizes. Consider the volatility and corrosivity of the liquid to choose between stainless steel or brass materials. Depending on the required measurement accuracy, opt for a mechanical stopwatch model or a digital timer model, with the cup volume typically fixed at 44 milliliters.
