Specifications

Large-screen LCD display, automatic testing, with a standard weight, automatically detects the interfacial tension, tension test

Product standard:
1,The instrument is designed GB/T6541-86 (1991) “Test Method for Interfacial Tension of Oil against Water by the Ring Method”.
2, its main use is to determine the interfacial tension between mineral oils and water under non-equilibrium condition (Liquid-Liquid interface), and be used to determine interfacial tension of various liquids (Liquid-Gas interface).
3,The instrument load bearinglarge LCD screen and blank button, So it has the characteristics of automatic, reliable, simple and with good repeatability. As long as you turn on the instrument and operate the instrument as per the prompt of menu, you can complete the test as per the prompt. In addition, it has function of automatic temperature compensation, clock control, printing, and automatic average value calculation.
