Compact tensiometer with perfect control and new methods
The Du Noüy-ring/Wilhelmy-plate method for the measurement of surface and interfacial tension in liquids is an established method for the characterization of surfactant solutions, oils and other liquids.
With the TD5 and its powerful Surface Meter software you have full control of the measurement as you see all raw data in real time. On top of this, the TD5 offers unique methods like the drop adhesion force measurements. The latter is of specific interest as it allows to directly measure the liquid-solid interactions. With this and other features the TD5 is one of the most compact research-grade tensiometer on the market.
