Results should be reported in Zahn-Seconds at a specified temperature for a particular cup. The orifice diameter of Zahn cup may be a little different from standard requirements due to some uncontrollable factors during manufacturing process.But we ensure the flow time conforms to standards. Hence, a precision stopwatch is required.Ģ. This method is ideal for measuring the consistency of paints, varnishes and similar products. 2 Dip Cup is a small U-shaped cup suspended from a looped wire. Both the Zahn Cups and the Iwata Cup are based on measuring the Flow of liquid in seconds. 2 Viscosity Dip Cup Certified Range: 23-231cSt Elcometer 2210/2. 2 Viscosity Dip Cup Certified Range: 23-231cSt Elcometer 2210/2. viscosity cup will help you accurately measure your material thickness for perfect thinning/reducing. ■ Details of each Zahn Cups Details/Zahn cupġ. ■ Volume of Cup:44ml ■ Length of Handle:40☐.1mm ■ Height of Cup:58☐.1mm ■ Measurement Temperature:25℃☑℃ The second shown is the time of the liquid flow, which is also the flow viscosity of that liquid.Įvery Biuged’s Zahn cup has its own coefficient “K”, which is marked on the cup body. As soon as there is a first “break” of the flow, stop the stopwatch. Immediately start the stopwatch when the finger is released. Prepare a Digital stopwatch and set zero. A ring at the Zahn Cup handle allows the cup to be hanged perpendicularly(still with the finger stopping any liquid flow out). It 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. Their orifice diameters are set at the factory for appropriate results with applicable NIST traceable Newtonian oils. Boekel cup type viscometers measure viscosity in the 18. At the center of this handle is a finger-ring for holding the cup in a vertical position during use. Description Quickly measures the viscosity of liquids such as paint, lacquer, varnish, syrup and oil. The Stainless Steel Cups are molded precisely and the orifices are precision drilled using high-speed CNC drilling.Įach cup has a 12-inch loop handle to allow the cup to be dipped by hand into a liquid container. They are produced according to ASTM D 816, ASTM D 1084,and ASM D 4212. Precisely Drilled and tested with Standard OilsĬhoose the cup you desire in the above dropdown menu.LR 126 Zahn Cups can be used to quickly measure the viscosity of liquids such as Paint, Ink, Varnishes, Syrup and Oil.The allowed deviation on a random pulled certificate is 85 times less than the Allowed Deviation! Our Zahn Cup comes with a Certificate that states and measures multiple times the Orifice Size, and Flow time at two positions.Cheap knockoffs available through Amazon or EBay or Aliexpress are not the same as when purchased through reputable supplier like us that stand behind their product. Like all measurement equipment and instruments, employees must be taught to perform the test correctly and repeatably.After lifting the Zahn cup out of the liquid, the stopwatch is started to measure the time until the liquid streaming out of the Zahn cup stops flowing as a stream and breaks up, this is the corresponding "efflux time". To determine the viscosity of a liquid, the Zahn cup is dipped and completely filled with the liquid. Large number cup sizes are used when viscosity is high, while low number cup sizes are used when viscosity is low. There are five Zahn cup specifications, labeled Zahn cup #, where # is the number from one through five. Our Zahn Cups are manufactured to measure the viscosity of liquids in Zahn seconds "the time required for a steady stream to stop flowing from the calibrated orifice at the bottom of the cup". A stain-less steel handle is affixed for handling. Zahn cups feature a stainless-steel shell with a tiny drain hole (orifice) in the center of the cups bottom. Portable and light-weight, they are utilized in workshops, factories, and laboratories to measure paint, ink, syrups, oil, laquer, varnish in many industries. Zahn cups (2 Zahn or 3 Zahn) are very commonly used to measure the viscosity range of flexo inks, gravure inks, and coatings in the graphic arts industry. Zahn Cups are used to measure the viscosity of
