Each cup has a 12-inch loop handle to allow the cup to be dipped by hand into a liquid container. At the center of this handle is a finger-ring for holding the cup in a vertical position during use. Results should be reported in Zahn-Seconds at a specified temperature for a particular cup.

  • Conversion of Zahn-Seconds to Centistokes:
    Centistokes = K * efflux time - (C / efflux time)
  • Conversion of Centistokes to Centipoise:
    Centistokes x Specific Gravity

             Conversion Factors:     K = 4.18             C = 760


Guide to Viscosity Measurement

Viscosity is an important property of liquids to determine how they flow, spread, or level under certain conditions. It can be defined as a liquid’s internal resistance to flow. Being able to measure the viscosity will allow to predict the behavior in a process or an application. When applying a paint by roll application the paint viscosity will strongly influence the amount of paint applied per surface area, thereby determining both yield and hiding power. It is crucial for liquid products to undergo a viscosity measurement in incoming and outgoing QC.
