Direct reading—no calculations needed—circular scale allows direct reading in dyne/cm

  • Measure surface tension and interfacial tension in oils, detergents, serums, colloidal suspensions, chromium solutions and more
  • For closer control of process and product quality
  • Surface tension measurements can be reproduced within ±0.05 dyne/cm
  • Compact unit comes with carrying case for easy transport
  • Stable—unit is mounted on a cast tripod with leveling screws

Precision Tensiometer

  • Measures surface tension between a liquid and air
  • duNouy ring is placed below liquid surface
  • Ring is pulled upward and force is measured in dynes/cm
Interfacial Tensiometer
  • Measures surface tension at the boundary of two liquids
  • Force needed to break up through the surface of the higher density liquid or down through the boundary is interfacial surface tension
