This instrument is specified for determining interfacial tension of oil against water by the ring method in ASTM Method D971 and solutionsof surface-active agents in ASTM Method D1331. It is also specified for testing synthetic rubber lattices in ASTM Method D1417 and determing the surface tension of industrial water and industrial wastewater in ASTM Method D1590 (To name a few).

Main unit, Laptop PC, software provided on CD, Platinum plate or DuNouy Ring (choose 2), Glass lab dishes for surface tension (x2), Calibration weights (200mg x2), built in Level, Alcohol lamp, Forceps, and operation manual.

Features:
◆ ­Fully automatic operation by single command button
­◆ ­For QC use, repetition of measurement can be preset
­◆ ­For surface solutions, graph of variations over time can be plotted
­◆ ­For R&D use, functions of graph overwriting and data converting to a spreadsheet can be prepared
◆ ­­Measurements of lamella length and liquid density are available in addition to surface/interfacial tension
