Cert. Zahn Type Cup No.3

• Range in Centistokes: 150 - 830
• Range in Seconds: 20 - 80
• Certificate included

Features

• Ideal for in-plant viscosity measurement tests
• Easy to use
• Precision made for reproducible results
• Orifice diameters adjusted at the factory for appropriate results with applicable NIST traceable Newtonian oils

Procedure

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. Results should be reported in Zahn-Seconds at a specified temperature for a particular cup.

• Conversion of Zahn-Seconds to Centistokes (ASTM D 4212):
  Centistokes = K * (efflux time - C)

• Conversion of Centistokes to Centipoise:
  Centistokes x Specific Gravity

  Conversion Factors:     K = 11.7            C = 7.5
