K100 Kruss

Force Tensiometer – K100. The universal instrument for analyzing surfactants and solid surfaces. Our universal Force Tensiometer perform high-precision, automatic and reliable measurements of surface tension and interfacial tension, critical micelle concentration (CMC). 3, Difference of surface tensiometer made by different manufactory. Note: 1, Test method of update speed of balance is acquiring data from balance versus times about several seconds, and at same time, we used stopwatch to record times; after then, calculating speed of.

High-quality components for precise measurements

K100 Kruss

The principal measuring methods used by the K100 are based on the precise measurement of the force which occurs when wetting a measuring probe or a solid sample. We use a special force sensor with a particularly high resolution for the instrument in order to obtain reliable, accurate measurements, for example for determining surface and interfacial tension or contact angle. To ensure accurate measuring results, we use measuring probes such as rings and plates with highly accurate contours. This guarantees an accurate correlation between measured force and the surface or interfacial tension.
