It is done by filling up the volume of Zahn Cup with the required liquid, and then used a index finger 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.Its orifice diameters adjusted at the factory for appropriate results with applicable NIST traceable Newtonian oils. 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.NT 102 Zahn Cups can be used to quickly measure the viscosity of liquids such as Paint, Ink, Varnishes, Syrup and Oil. It is produced according with ASTM D 816, ASTM D 1084,ASM D 4212.The Stainless Steel Cups are molded precisely and the orifices are precision drilled using high-speed CNC drilling.Each Zahn cup serves as an accurate measuring system to ASTM D4212 standards, and. A number in parentheses indicates the year of last reapproval. Please call for information on certified cups. Our cups are available in various sizes to meet your labs specific needs. Standard Test Method for Viscosity by Dip-Type Viscosity Cups1 This standard is issued under the fixed designation D4212 the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year of last revision. EZ® cups qualify for certification under the requirements of MIL STD 45662A or ANSI/NCSL Z540-1. D1200 Test Method for Viscosity by Ford Viscosity Cup. Never use silicone-based oils to calibrate viscosity cups they leave a residue that alters performance. It is constructed of a solvent and corrosion resistant stainless steel and consists of a bullet-shaped cup which can hold up to about 48 ml. Standard Test Method for Viscosity by Dip Type Viscosity Cups. Viscosity Cup ASTM D1084 D4212 Immersion Zahn TQC.

Use the appropriate calibration oils to assure continued accuracy. Astm D 4212 Zahn Cups EZ Zahn Dip Viscosity Cup Instruction Manual Cole Parmer. To convert Zahn-Seconds to centistokes, refer to ASTM D4212, D816, and D1084 Centistokes × Specific Gravity Centipoise See also Stormer viscometer Ford viscosity cup Flow cups References 'Gardco :: S90 Zahn Viscosity Cups'. EZ® cups receive the highest quality recommendation from Diversified Enterprises.Įach cup is supplied with a conversion chart for drain time in seconds vs. The precision workmanship and unique design allow calibration tolerances within 3%. Handles are offset from the side of the cup and secured below the rim, eliminating errors due to drainage from the support surfaces.
