An overview,
This automatic interfacial tensiometer, according to gb6541-86 "Petroleum products oil to water interfacial tension determination method" (ring method) standard requirements, measurement of various liquid surface tension (liquid-gas interface) and mineral oil and water interfacial tension (liquid-liquid interface). The instrument uses a large screen dot matrix LCD display, the whole Chinese menu prompt no identification button, high degree of automation, reliable work, good repeatability, the operation is very simple, just after starting the operation according to the menu prompt, you can complete all the tests. The instrument has automatic temperature compensation, time clock control, power off storage, printing, automatic average calculation, redundancy design RS232 interface can be directly connected with the computer parallel operation and directly transfer test results to the handheld computer and other new functions.
