Gardco Stainless Steel Calibrated EZ Zahn Viscosity Cup for Viscometer Size No. 2

  

Gardco EZ2 Stainless Steel Calibrated EZ Viscosity Cup for Viscometer, Size No. The EZ Viscosity Cup Series is a logical and necessary outgrowth of the standardization studies on the Zahn Signature Viscosity Cup and similar cups for the promotion of this most popular type of viscosity measuring instrument as a national and international standard. Not only has this cup been improved with respect to earlier produced cups and designed to comply to the requirements of ASTM D4212 but, in addition, each EZ Viscosity Dip Cup is furnished with a table which permits conversion between efflux time in seconds to the nearest tenth of a second to viscosity in centistokes. This table is particularly useful in determining efflux time in seconds when viscosity in centistokes is known.

The EZ Viscosity Cups are produced to very close mechanical tolerance in elaborate jigs and fixtures. Such equipment not only insures that each cup is correctly produced but also that all cups are identical. All parts of the flow cup are of stainless steel except for the name plate. The following table provides operating range specifications, dip cup midrange sensitivity and recommended Canon calibration oils (standards).

Following this table are graphs and mathematical formulas that relate efflux time in seconds to centistoke viscosity.
