It is commonly a stainless steel cup with a tiny hole drilled in the\ncentre of the bottom of the cup. There is also a long handle attached to the\nsides. There are five cup specifications, labelled Zahn cup x, where x is the\nnumber from one through five (see table below). Large number cup sizes are\nused when viscosity is high, while low number cup sizes are used when\nviscosity is low. They are manufactured in accordance to ASTM D 4212, ASTM\nD1084 and ASTM D816To determine the viscosity of a liquid, the cup is dipped\nand completely filled with the substance. After lifting the cup out of the\nsubstance the user measures the time until the liquid streaming out of it\nbreaks up, this is the corresponding \"efflux time\". On paint standard\nspecifications, one denotes viscosity in this manner: efflux time, Zahn cup\nnumber. One can convert efflux time to kinematic viscosity by using an\nequation for each cup specification number, where t is the efflux time and v\nis the kinematic viscosity in centistokes.

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.\u003c\/li\u003e\n         \u003cli\u003eIt is done by filling up the volume of Zahn 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 Zahn Cup 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.\u003c\/li\u003e\n         \u003cli\u003eZahn Cup can be used to quickly determine the viscosity of printing ink, dyes, coatings, experimental solvents, leather paint, oil, grease, food, and other mobile liquids in the printing industry such as paint, varnish, wet enamel, gravure, relief, lithography, flexography, silk plate, etc. Zahn Cup is often used as a fast viscosity measuring tool in workshops and on the spot.\u003c\/li\u003e\n  \u003c\/ul\u003e","brand":"TOSYUWIR","offers":[{"title":"Default Title","offer_id":43977501966516,"sku":"B0CQQN9N81","price":210.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0595\/9906\/1172\/files\/B0CQQN9N81.jpg?v=1775761669","url":"https:\/\/auspowers.com\/products\/zahn-cup-viscosity-cup-dip-type-viscometer-flow-cup-44-ml-no-2-no-2","provider":"AusPower Australia","version":"1.0","type":"link"}
