The compact scientific instrument with perfect control and new methods

The compact and precise TD5 tensiometer is the ideal instrument for your research, quality control, and product development. With the TD5, you can measure not only standard methods such as the Du-Noüy ring or Wilhelmy plate method for measuring surface and interfacial tension in liquids to characterize surfactant solutions, oils, and other liquids, but also drop adhesion force and density - all in a very compact device that does not require the entire laboratory bench. Thanks to the user-friendly Surface.Meter software, you have the ability to fully control the measurement and monitor the raw data in real-time, so you can rely on the results at any time. One highlight of our TD5 is the unique drop adhesion measurement, which allows you to directly measure the interactions between liquid and solid.

With the TD5, you get one of the most compact tensiometers for research purposes on the market. Precise data in a compact format.


Special Features:
