Interfacial Surface TensioMeter

The surface Tensiometer analyzes wettability and spreadability by measuring the interfacial tension between liquid and gas or between liquids. It directly reads tension values using the ring method or pendant drop method, and is used for ink adhesion testing, coating leveling assessment, and cleaning agent effectiveness verification.
Selection
When selecting, focus on the measurement range covering the actual sample tension values, ensure the precision meets testing requirements, and consider the sample temperature control needs. The instrument materials should be resistant to chemical corrosion, with a simple and user-friendly operation interface, and stable supply of consumables.
