Ultrapure Water Surface TensioMeter

The pure water surface Tensiometer evaluates wettability by measuring the intermolecular forces at the liquid surface, directly reading tension values using the ring or plate method. It is used to detect water purity, monitor cleaning effectiveness, and verify surfactant performance, commonly applied in adhesion testing of printing inks and plastic coating treatments.
Selection
When selecting, consider a measurement range that covers the conventional 72 mN/m, with an accuracy of 0.1 mN/m and equipped with temperature compensation. Prioritize a stable and corrosion-resistant material structure, a simple operation interface, and comprehensive calibration tools. Based on sample characteristics, optional automatic sampling or viscosity adaptation modules should be selected to ensure data repeatability meets basic testing requirements.
