Ring Method Surface Tension Analyzer

The surface Tensiometer using the ring method measures the force required to lift a metal ring from the surface of a liquid, calculating the surface tension based on the relationship between the liquid's surface tension and the pulling force. It is used in industries such as coatings and inks to test the wettability and stability of liquids, guiding formulation adjustments.
Selection
When selecting, consider matching the measurement range to the sample tension, ensuring precision meets standard requirements, choosing materials that are corrosion-resistant to suit the test liquid, prioritizing ease of operation, and evaluating maintenance costs and manufacturer technical support.
