ISO viscosity cup (flow cup)
ISO cup profile
ISO cup is a desktop viscosity cup with a holder, according to different measurement aperture designed five different models: 3, 4, 5, 6, 8 (to be customized), the measured aperture were 3mm, 4mm, 5mm, 6mm, 8mm. Putin ISO Cup production designers meet the standards ASTM D 5125, ISO 2431, is an essential laboratory testing viscosity testing equipment.
The ISO cup is made of anodized aluminum and has a bore made of stainless steel for measuring the viscosity of paints, varnishes and other similar products.

Definition of viscosity and viscosity cup
Viscosity: The ability of a liquid to obstruct its tendency to flow is called viscosity. For the paint industry, viscosity is a key parameter.
Viscosity cup: the liquid flows through the nozzle, usually using this method can be relative to its viscosity measurement and grading.
Kinematic viscosity values are usually expressed as the number of seconds in the stream, and can also be converted to units of Centistokes through a viscosity conversion disc.
Viscosity unit
Kinematic viscosity values are usually expressed as the number of seconds elapsed before the end of flow, and can also be converted to units of Centistokes through a viscosity conversion disk.
Kinematic viscosity in Stokes, Stokes, when the fluid viscosity 1P (Po), the density of 1g / cm3 kinematic viscosity of 1 Stokes.
cSt is an acronym for centistokes, called the Cousins, which is 1 percent of a Stokes. The cSt is the smallest unit of kinematic viscosity.
Precautions
Need to use a relatively high precision stopwatch.
