FORCE TENSIOMETER, K20

The versatile semi-automatic tensiometer for quality control

It is the specialist for quality control-everywhere that surfactants are used and for measuring surface and inter facial tension of liquids using the Wilhel my Plate or the Du Noüy Ring method. In addition, it is able to determine the density of liquids.

The motorized sample stage can be manually as well it is driven smoothly by an electric motor for quick measurement. It can be powered by rechargeable batteries, so it is suitable for flexible use as a portable stand-alone instrument.

It is available as the manual standard version K20S and the semi-automatic instrument K20.
