Four-Cup viscosity Cup

The Zahn viscosity cup determines viscosity by measuring the time it takes for a fluid to flow through a standardized orifice to discharge a fixed volume. It is used for viscosity testing of fluids such as paints and inks, making it suitable for on-site rapid testing and quality control.
Selection
When selecting a Zahn viscosity cup, consider the viscosity range of the fluid being tested and match it with the corresponding model's outflow aperture diameter. Choose stainless steel or brass materials based on the usage scenario, with a standard 100ml capacity cup commonly used in conventional laboratories. Pay attention to the accuracy of the cup's aperture and the calibration certificate.

Handheld viscosity cups are used for rapid assessment of paint viscosity at construction sites.
A handheld viscosity cup is a portable tool used to quickly assess the viscosity of coatings at construction sites. It operates based on the flow-out time method, calculating viscosity by measuring the time it takes for the coating to flow out of the cup's orifice. It is suitable for Newtonian or approximately Newtonian fluids.

Key steps for measuring the efflux time of varnish using a viscosity cup method
This article introduces the method for measuring the outflow time of varnish using a viscosity cup. The principle is based on Poiseuille's law, where viscosity is estimated by recording the time it takes for the liquid to completely flow out from the small hole at the bottom of the cup—longer times typically indicate higher viscosity.
Types and Selection of Paint Viscosity Cups
As a simple tool for measuring the liquid outflow time, the viscosity cup is mainly categorized into various types such as the Tu-4 cup, ISO cup, Ford cup, and Zahn cup, based on standards from different countries and regions. These cups differ in orifice size, capacity, and the types of fluids they are suitable for.
