Tensiometers TD 4

Automatic measurement of surface and interfacial tension 

TD 4 is used for automatic measurement with high reproducibility. Simple menu navigation and intuitive operation characterize the TD 4. Even demanding samples can be handled by simple parameter adjustments via the Tensio.Touch user interface.

TD4— compact and precise for the measurement of surface and interfacial tension


For researchquality control and product development

The ring/plate method for the measurement of surface and interfacial tension in liquids is an established method with future potential: The increasing demand for surface-active additives and their detection in quality control requires automated and user-friendly devices. As a stand-alone device the compact ring/plate tensiometer TD4 offers everything you require for research and development, as well as for quality control.
