The EasyDyne instrument is a tensiometer for measuring surface and interfacial tension of liquids using the Wilhelmy Plate or the Du Noüy Ring method. In addition, it is able to determine the density of liquids.

The instrument combines ease of use, flexibility and robustness. Special attention during development was turned to the simple operation of the instrument with making no concessions elsewhere.
The motorized sample stage can be adjusted manually as well to ensure quick preparation of measurements while it is driven smoothly by an electric motor during the measurement. Measurements are carried out automatically, controlled by the built-in micro processor. Statistical and correction methods are implemented so that the final measuring results can be read directly from the illuminated graphical display. Calibration has to be done just once independently of the measuring method, since all parameters and calibration data are saved automatically. For accurate measuring results the instrument is equipped with a windshield to avoid influence from air flow. The large sample compartment together with the long travel distance of the stage ensures easy handling and use of large samples. The illumination assists during the sample positioning.

Because of the robustness, ease of use and short measuring times the EasyDyne is excellent for quality control applications.
