Viscosity Flow Cups are used for measuring the consistency of paints, varnishes and other similar products. Each TQC viscosity cup is made under continuing quality control procedures and provided with an engraved unique serial number. The design of the cup and orifice eliminate hard to clean recesses. The inner dimensions are according specified standards. Since not all orifices are specified in the standards, additional orifices have been designed to comfort unspecified applications. Almost each cup is available in titanium anodized aluminum and stainless steel. All orifices are fixed and made of stainless steel.
