Hold Dia Zahn Dip Type Viscosity Cup

Features:
Zahn Cup is a viscosity measurement device widely used in the paint industry. Use large number cup sizes when viscosity is high, use low number cup sizes when viscosity is low.
To determine the viscosity of a liquid, the cup is dipped and completely filled with the substance. After lifting the cup out of the substance the user measures the time until the liquid streaming out of it breaks up, this is the corresponding "efflux time"
On paint standard specifications, one denotes viscosity in this manner: efflux time, Zahn cup number
Conversion
One can convert efflux time to kinematic viscosity by using an equation for each cup specification number, where t is the efflux time and V is the kinematic viscosity in centistokes
Zahn Cup #1: V = 1.1(t - 29)
Zahn Cup #2: V = 3.5(t - 14)
Zahn Cup #3: V = 11.7(t - 7.5)
Zahn Cup #4: V = 14.8(t - 5)
Zahn Cup #5: V = 23t
Package includes:
1x viscosity cup
