Oil Film Viscosity Cup

The oil film viscosity cup reflects viscosity by measuring the time it takes for fluid to flow out completely through a small hole at the bottom of the cup. The fluid flow time is proportional to the viscosity, making it suitable for on-site rapid testing of the fluidity of coatings, inks, and other materials. It is easy to operate and ideal for production sites and quality control.
Selection
When selecting an oil film viscosity cup, it is essential to match the viscosity range of the fluid being tested and choose the appropriate cup type with the corresponding orifice diameter according to standards. Consider the fluid characteristics, such as evaporation rate: metal cups are suitable for solvent-resistant applications, while plastic cups are ideal for measuring water-based materials. Verify the calibration marks and regularly clean the orifice to prevent clogging.

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.
