Viscosity Flow Cups
The Rhopoint Flow Cups are designed to accurately measure the viscosity of paints, inks, varnishes and similar products.
What is viscosity?
The term “viscosity” is a parameter that describes a fluids resistance to flow. This resistance is a measure of the friction and the forces of interaction between the layers of a fluid. This friction is apparent when one layer of fluid is made to move against another The greater the friction, the greater the amount of force required to cause the movement – known as “shear”.
The process of flow through an orifice can often be used as a relative measurement and classification of viscosity. This measured kinematic viscosity is generally expressed in seconds of flow time which can be converted into centistokes (cSt) using a viscosity calculator.
Manufactured from high grade aluminium alloy with stainless steel orifices (where indicated), the Rhopoint Flow Cups are available with a range of UKAS / ISO 17025 certified standard oils to confirm the flow cup is measuring within specification.

Answers to common questions about our instruments and measurements
What glossmeter do I need?
Identify the surface that you wish to measure. Is it a flat surface? If so, it can be measured with a traditonal glossmeter. Curved surfaces
What is RSpec?
RSpec is the peak reflectance measured over a very narrow angular band in the specular direction (+/-) 0.0991º. RSpec is very sensitive to any texture
