This instrument is designed with ISO 6295, ISO 1409, ASTM D1417, EN 14370 etc “Test Methods for Interfacial Tension of Petroleum Products between Oils and Water (Ring Methods) ”.
It is suitable to determine interfacial tension between mineral oils and water under non-equilibrium conditions (Liquid-liquid interface). It can also be used to determine surface tension of various liquids (liquid-gas interface).
With an advanced electromagnetic balanced force sensor, operator can get high precise and reproducible testing result.
Large 5" touch-screen can show the current environment temperature, current tension, peak tension, the equivalent tension tec, easy to operate.

Technical Specification
Built in two testing methods, platinum ring and platinum plate, the operator can choose anyone or both
Full automatic operation can eliminate all human error. Platinum plate can lock liquid interface automatically, platinum ringshows tension curve, and peak tension will be locked automatically, without any conversion, the screen tension will show the values directly.
Calibrates automatically in full range: weights weight, pure water tension and ethanol tension
With an elaborate ball screw, the lift system is low-noise, and its rising & falling speed can be adjusted.
The lifting bracket is designed to install and disassemble the platinum ring and platinum plate easily. Operator can calibrate force value anytime by standard weight
Peeling function by one button, no drift to zero point and no beat for showing data
Automatic compensation for environment temperatute: taking the water and ethanol as standard, the tester converts automatically the sample’s tension value under 20 °C
