Tensiometers

DU-NOUY Method Interfacial Tensiometer

Interfacial, DU-NOUY, ring method, ASTM approved. Tensiometer gives precise readings of both surface and interfacial tensions by the ring method to values reproducible to within 0.05 dyne/cm. This instrument is specified for determining interfacial tension of oil against water by the ring method in ASTM Method D-971 and solutions of surface-active agents in ASTM Method D-1331. It is also specified for testing synthetic rubber latices in ASTM Method D-1417 and determining the surface tension of industrial water and industrial waste water in ATM Method D-1590.**The graduated dial reads in both...
