I. Overview
Automatic interfacial tension tester, in accordance with GB6541-86 "Petroleum
products oil to water interfacial tension measurement method" (circle method)
standard requirements, measure the surface tension of various liquids (liquid-gas
interface) and the interface between mineral oil and water Tension (liquid-liquid
interface). The instrument adopts a color touch screen display and a non-marked
button with full Chinese character menu prompts. It has a high degree of automation,
reliable work, good repeatability, and extremely simple operation. All tests can be
completed by simply pressing the menu prompts after turning on the machine.
