What does a Zahn cup measure?

viscosity
The Zahn Cup-Type Viscosimeter is a portable device for quickly measuring the viscosity of such fluids as paint, lacquer, varnish, syrup, creams and oil.

Who invented the Zahn cup?

E. A. Zahn
The Zahn Cup is produced not only by different suppliers in the United States but also in countries throughout the world such as England, France, Italy, and West Germany. However, The Paul N. Gardner Company is the only licensed producer by the inventor E. A. Zahn. 12.

What is a Zahn second?

The viscosity of a liquid, when measured by the Zahn viscosimeter, is expressed in Zahn seconds; that is, the time required for a definite volume (44cc) of liquid to flow through the orifice in the bottom of a metal cup. The unit of measurement is Zahn seconds.

How do viscosity cups work?

The viscosity is thicker when the finish is cold and thinner when the finish is warm. To measure viscosity dip a viscosity cup into a finish so the cup is full. Then lift the cup out of the finish and begin timing the drainage with a stopwatch.

How do you convert centistokes to Centipoises?

Centipoise = centistokes x specific gravity where specific gravity is assumed to be 0.8 (except for water). To find the exact cp of your fluid: cp = cSt x (weight per gallon x 0.120).

Are all viscosity cups the same?

There are a variety of viscosity cup sizes and types which will cover different ranges of viscosity. They use the amount of time the material takes to flow through the cup to help you determine the viscosity in centipoise. However a lot of times you may have a thicker coating with a higher viscosity.

Are all paint viscosity cups the same?

What is B4 viscosity cup?

B4 cup viscosity is a widely instrument used to measure the viscosity of adhesives. Viscosity is the measure of adhesive’s resistance to flow.

What do I need to know about choosing a coating viscosity cup?

To select a viscosity cup that will match the needs of your painting you can check the coating data sheets for your coatings and see if a cup is referenced. You can then consider a viscosity cup conversion chart that shows the range of viscosities a particular cup can measure.

Is cSt same as CPS?

The proper way to identify oil viscosity, in cgs units, is either in centistokes (cSt), or more appropriately, centipoise (cP). Although the two terms are regularly interchanged, which is further complicated due to 1 cP being equal to 1 cSt, they are in fact two slightly different terms.
