Zahn Cup

Synonym : Zahn Viscosity Cups, Zahn Viscosity Dip Cups

Category: Coating Inspection, Viscosity Flow Cups

Caltech India offers Zahn Cup. BGD 126 Zahn Cups can be used to quickly measure the viscosity of liquids such as Paint, Ink, Varnishes, Syrup and Oil. They are produced according to ASTM D816, ASTM D1084 and ASTM D4212. The Stainless Steel Cups are molded precisely and the orifices are precision drilled using high-speed CNC drilling.

Each cup has a 12-inch loop handle to allow the cup to be dipped by hand into a liquid container. At the center of this handle is a finger-ring for holding the cup in a vertical position during use. Their orifice diameters are set at the factory for appropriate results with applicable NIST traceable Newtonian oils.

It is done by filling up the volume of Viscosity Cup with the required liquid and then placing an index finger over the orifice to stop any flow out of the liquid. A ring at the Viscosity Dip Cups handle allows the cup to be hanged perpendicularly(still with the finger stopping any liquid flow out). Prepare a Digital stopwatch and set zero. Immediately start the stopwatch when the finger is released. As soon as there is a first “break” of the flow, stop the stopwatch. The second shown is the time of the liquid flow, which is also the flow viscosity of that liquid.

A zahn cup is also known as a viscosity cup or zahn cup viscometer. There are lot of different zahn cup sizes available with us. We are leading manufacturer, supplier, exporter, trader of Zahn Cup for buying in India and Worldwide. To know more about the zahn cup price for purchase, contact us.

Every Biuged’s Zahn cup has its own coefficient “K”, which is marked on the cup body.

Fact Viscosity = Testing viscosity x K

Main Technical Parameters:

  • Volume of Cup:44ml
  • Length of Handle:40±0.1mm
  • Height of Cup:58±0.1mm
  • Measurement Temperature:25℃±1℃

NOTE:
Both the Zahn Cups and the Iwata Cup are based on measuring the Flow of liquid in seconds. Hence, a precision stopwatch is required.

Results should be reported in Zahn-Seconds at a specified temperature for a particular cup. To convert Zahn-Seconds to centistokes, refer to ASTM D4212, D816 and D1084

Centistokes x Specific Gravity= Centipoise
