Ring method interfacial TensioMeter

The Du Noüy ring Tensiometer measures the maximum force when a platinum ring is pulled from the liquid surface, with the force being proportional to the interfacial tension. It is used to detect the surface tension of liquids or the tension between two-phase liquids, controlling spreadability in coatings and inks, and monitoring stability in emulsion production.
Selection
When selecting, consider the sample properties: high-viscosity liquids require the ring method; pay attention to the matching of the measurement range with common tension ranges; the precision of the balance affects data accuracy; the platinum ring specifications should be compatible with the container size; the operating environment must be vibration-proof; and the calibration function ensures long-term reliability.
