Falling Ball Viscometer | Brookfield | DIN 53015
Falling Ball Viscometer Models KF30 and KF40, complies with the German industry standard DIN 53015. The measuring principle, according to Höppler, is to determine the falling time of a ball in a cylindrical glass tube filled with liquid. The working angle of the falling tube in the KF30 is fixed in the DIN 53015 position of 80° relative to horizontal. The water jacket, surrounding the falling tube, when connected to a Brookfield circulating temperature bath provides for precise temperature control of the sample.
KF40 can be angled at 50°, 60°, 70° and 80°.
Falling Ball Viscometer – FEATURES AND BENEFITS

- 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
Falling Ball Viscometer HOW IT WORKS
The Falling Ball Viscometer is based on the measuring principle by Höppler for simple but precise dynamic viscosity measurement of transparent Newtonian fluids. The basic concept is to measure the elapsed time required for the ball to fall under gravity through a sample-filled tube inclined at an angle*. The tube is mounted on a pivot bearing which quickly allows rotation of the tube 180 degrees, thereby allowing a repeat test to run immediately. Three measurements are taken and the average time it takes for the ball to fall is the result. A conversion formula turns the time reading into a final viscosity value.
The Falling Ball Viscometer is used for quality control in various industries as well as in academic institutions to illustrate scientific method. The ease of use and straightforward method for recording time measurements ensures meaningful
*Model KF40 can be angled at 50, 60, 70 and 80 degrees.
