The Falling Ball Viscometer...
Product Announcement from Brookfield Engineering Laboratories, Inc.
The Falling Ball Viscometer utilizes the simple but precise Hoppler principle to measure viscosity. 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 is converted into a final viscosity value in centipoise.
The Falling Ball Viscometer is used for quality control in various industries as well as in academic institutions to illustrate scientific method. It can be used with a Brookfield Circulating Bath for rapid sample temperature control which provides more accurate and repeatable results.
Model KF10 has a fixed angle of 80 degrees in accordance with the DIN 53015 and the Model KF20 provides variable angle settings for flexibility in testing a broader range of materials. Both models include a set of six balls, each with a separate viscosity measurement range and a temperature probe.
