Présentation du produit
The Automatic Interfacial Tension Tester is designed to measure both the surface tension of liquids (at liquid-gas interfaces) and the interfacial tension between mineral oil and water (at liquid-liquid interfaces), in full compliance with the GB6541-86 standard — "Method for Determination of Oil-Water Interfacial Tension of Petroleum Products" (Ring Method).
Featuring a color touch screen display and clearly labeled Chinese menu prompts, the instrument offers a highly automated and reliable testing process with excellent repeatability. Operation is extremely simple: after powering on, all tests can be easily completed by following the intuitive on-screen menu instructions.
