Viscosity Flow Cup
Viscosity Flow Cup
Simple to use cups for the approximate measurement of apparent viscosity in a wide range of materials including paints, varnishes, lacquers, inks and other viscous products.
BS-ISO Viscosity Flow Cups are supplied to meet the requirements of BS3900 / IS 3944. Calibration of the Flow cup is traceable to the National Standards when supplied. The Flow cup is machined from brass material with removable stainless steel orifices.
The cup has been greatly reduced in weight by removal of excess metal on the lower portion of the cup adjacent to the orifice. This reduces errors due to possible temperature change imposed by the cup.
