Flow cups supply viscosity data generally expressed in seconds flow time when the fluid is flowing through a hole at a given temperature. Viscosity is calculated from this flow time to centistokes (cSt). Paint, ink, varnishes and similar industries use flow cups to calculate the viscosity quickly.
Supplied with certificate of conformity.
