Tensiometers

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 59951-25 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.
What' s Included:
a 6-cm platinum-iridium measuring ring, three extra torsion wires, and a carrying case.
