K20 is a robust, semi-automatic instrument for the precise measurement of surface tension and interfacial tension. The density of liquids can also be measured.
Using the ring and plate method methods, it produces reliable measurements for the routine quality assurance of all types of surfactant solutions and interfacial processes.
Complies to ASTM D 971 and IEC 62961 international methods.
For flexible onsite usage, it has a long-life battery operation without use of a computer, an integrated memory and low instrument weight
