Tensiometer

Ideal for measuring the surface tension of oils, detergents, colloidal suspensions, and chemicals
→ Measure surface tension in 15 to 30 seconds
→ Direct-reading scale in dyne/cm

Measure both the surface and interfacial tension of liquids. Range is 0 to 90 dyne/cm. Measurement values are reproducible to within 0.05 dyne/cm. These meters are specified for determining interfacial tension of oil against water by the ring method in ASTM D971, solutions of surface-active agents in ASTM D1331, testing synthetic rubber lattices in ASTM D1417, and determining surface tension of industrial water/wastewater in ASTM D1590.

Model 59951-20 reads surface tension and upward interfacial tension. Model 59951-25 measures both upward and downward forces on the measuring ring—great for testing two-phase liquids. Features graduated dial readings in both directions from 0 to 90 dyne/cm and a double vernier. Both the scales and the corresponding verniers have graduations and figures in different colors to indicate whether the force is in an upward or downward direction.

The tensiometer is mainly to test surface tension of all kinds of liquids just like water, oil liquid chemicals and so on. It is widely used in the petroleum, chemical industry, research department and university. This instrument is composed by platinum ring , torsion wire, differential transformer and data procession system according to the ISO 1409 and ASTM D971 standard
