The DuNouy Tensiometers are proven instruments for measuring surface tension quickly, in 15-30 seconds.
They are ideal for checking liquids, including oils, detergents, serums, colloidal suspensions, chemicals and other products.
Ring method allows readings to be made in 15-30 secs. (Ideal for colloidal suspensions which exhibit rapid changes in surface tension.)
Specified for determining interfacial tension of oil against water by the ring method in ASTM Method D971 and solutions of surface-active agents in ASTM Method D1331.
Specified for testing synthetic rubber lattices in ASTM Method D1417 and determining the surface tension of industrial water and industrial wastewater in ASTM Method D1590.
Circular scale is graduated in dynes/cm eliminating the need for mathematical calculations.
Improved technique allows accurate readings to be reproduced within ±0.05 dyne/cm.
Compact unit is portable and comes with a carrying case for easy transport.
Unit is stable and mounted on a cast tripod support with convenient leveling screws.
Surface and interfacial tension measurements are extremely important in the control and improvement of: Absorption, cataphoresis, emulsification, osmotic, ressure, condensation, evaporation, miscibility, solubility

Unit comes completely assembled with torsion wire
Platinum-iridium ring
Metal case
