Falling Ball Viscometer

The Falling Ball Viscometer makes Newtonian measurements simple and easy!

The Höppler principle is used to measure the viscosity of Newtonian liquid by measuring the time required for a ball to fall under gravity through a sample-filled tube that is inclined at an angle. The average time of three tests is taken; the result is converted into a viscosity value using a simple formula.

Two models are available:

KF10 has a fixed angle of 80° and complies with DIN 53015

KF20 can be angled at 50°, 60°, 70° and 80°.


  • Pivot bearing allows for quick and easy tube rotation – ideal for repeat tests
  • Connection to circulating bath for temperature control of sample
  • Set of six balls to test a wide variety of samples
  • Complete with temperature probe
  • Accuracy 0.5% to 2.0% depending on ball being used
