Force Tensiometer – K20
The flexible tensiometer for basic quality assurance
Our Force Tensiometer – K20 is a robust, semi-automatic instrument for the precise measurement of surface tension and interfacial tension. Using the ring and plate method as the main tensiometric methods, it produces reliable measurements for the routine quality assurance of your surfactant solutions and interfacial processes.
Our K20 measures surface tension and interfacial tension based on the wetting force acting on a measuring probe. The instrument's precision force sensor and the measuring probes in the form of meticulously produced rings and plates ensure accurate and reproducible results. The density of liquids can also be measured very easily and precisely. The option of long-life battery operation, the integrated memory and the low weight of the instrument also enable our K20 to be used flexibly on site.
Simple, semi-automatic measurement
The simple manual operation of the sample stage and the large, illuminated sample chamber enable the sample to be quickly set up and positioned. When one of the pre-prepared measuring programs is started, the motorized sample stage moves to enable the measurement to be carried out conveniently and accurately. The speed and other
