MEASUREMENTS WITH THE IONIZER Measurement with two
dosing units
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.
Single Fibre Tensiometer K100SF
EXTREMELY ACCURATE
Precision in a new dimension: the PC-controlled measuring system K100SF
determines the surface and interfacial tension of liquids and solids with the highest
effectiveness and efficiency. The built-in ionizer ensures optimal measuring condi-
tions. The high accuracy of the measuring instrument guarantees the exact charac-
terization of the finest single filaments.
