Surface Tension Tensiometer

CSC Cenco 70535000 Du-Nouy Method Precision Tensiometer. This Upward Direction Tensiometer gives precise readings of upward interfacial and surface tensions by the ring method to values reproducible within 0.05 dyne/cm. This instrument is specified for determining interfacial tension of oil against water by the ring method of ASTM Method D971 and solutions of surface-active agents in ASTM Method D1331. It is also specified for determining the surface tension of industrial water and industrial wastewater in ASTM Method D1590.

Measurement: apparent surface tension
70535000 Measures surface tension between a liquid and air
70545000 Measures surface tension at the boundary of two liquids

Featuring:
~ RAPID MEASUREMENT: Ring method allows readings to be made in 15-30 seconds.
