Force Tensiometer – K100

The Multi-Talent

The K100 is the universal instrument among tensiometers. The measuring processes have been optimized and made more exact by a high degree of automation and the latest technical analysis standards.

The measuring accuracy of the K100 can be additionally increased by the use of the built-in ionizer. The high accuracy of the results and the flexible software control make the K100 the top-class tensiometer.

No Chance for Electrostatics - Measurements with the Ionizer

When conventional tensiometers are used to make sensitive measurements on small samples, single fibres or insulating plastics electrostatic forces of attraction occur between the solid and the liquid surface - the measured force or the detected surface height is incorrect.

KRÜSS has thought out a solution to this problem (and also applied for a patent for it): the use of an ionizer. This ionizes the air in the sample chamber for a short time and in this manner eliminates any electrostatic charges. The measurement can now be made without any interference with the highest degree of accuracy.
