Zahn Cups can be used to quickly measure the viscosity of liquids such as Paint,Ink,Varnishes,Syrup and Oil. Complies with ASTM D 4212 (Standard Test Method for Viscosity Cup Immersion)standards The 304 stainless steel thickened Cups are molded precisely and the orifices are precision drilled using high-speed CNC drilling. Viscosity is expressed in Zahn seconds which are correlated to viscosity in centistokes.Mainly in order to maintain the stability of the viscosity of the product in the process of use, so that the viscosity is always maintained at the set range to protect the color of the product effect. 100% Money Back Guarantee, you will never have to worry when you do business with us, we support every product we produce.
