A:Product Introduction:
DSHD-6541A Automatic Interfacial Tension Tester is designed according the National Standard of People's Republic of China GB/T6541-86 (1991) "Test Method for Interfacial Tension of Oil against Water by the Ring Method".
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).
DSHD-6541A Automatic Interfacial Tension Tester load bearing large 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,DSHD-6541A Automatic Interfacial Tension Tester has function of automatic temperature compensation, clock control, printing, and automatic average value calculation. It can connect to a computer through RS232 interface, So you can also send the test data to a handheld computer for analysis. In similar products, it is preferred.
