Zahn Cup Viscometers are a simple way to test product viscosity. A small orifice is at the bottom of the cup that restricts the flow to detect the viscosity.

• Quickly measures the viscosity of liquids such as paint, lacquer, varnish, syrup and oil.
• Boekel cup type viscometers measure viscosity in the 18 to 1725 centistokes range in 90 seconds or less.
• Five cups are available differing only in the size of the orifice
• Viscosity is expressed in Zahn seconds which are correlated to viscosity in centistokes
• Cup volume is 44 mL
• Compact and easy to use
• Rapid results
• Inexpensive
