Simple efflux type flow cups are used to measure and control the viscosity of paints, lacquers, inks and other viscous products.
Note: All viscosities and flow times quoted are approximate values at 25°C. Cup verification oils are supplied in a 500ml container along with a UKAS calibration certificate traceable to International standards (ISO 3104 and ISO 3105). The certificate quotes the viscosities of the oil at 20°C, 25°C and 30°C, along with the equation required to calculate intermediate values and (where applicable) Krebs units at 20°C, 25°C and 30°C.
