The Tensiometer K11 - ideal for measurement for surface tension and interfacial tension - combines easy handling with flexible application.
The large well-illuminated sample chamber can be opened wide and facilitates the exchange of sample liquid and measuring devices. The measuring data are shown on an easily readable tensiometer display and can either be printed or transferred to a PC.
