Digital Tensiometer for Interfacial Tension of Oil
Introduction:
This tensiometer is designed and made as per the National Standard
of People’s Republic of China GB/T6541-86 (1991) “Test Methods for
Interfacial Tension of Oil against Water by the Ring Method”. It is
suitable for measuring the non-equilibrium conditions of mineral
oil in water interfacial tension (Liquid-liquid interface). It can
also be used to determine surface tension of various liquids
(Liquid-gas interface)
Features:
1. This digital tensiometer uses a large LCD display, full Chinese
menu of unmarked buttons, high degree of automation, reliable,
reproducible, easy to operate, you just turn on the instrument and
operate it as per the menu prompts, and then you can complete whole
test.
2. The tensiometer has functions of temperature compensation, cl℃k
control, power-off storage, printing, and average value
calculation. It can communicate with a computer through RS232 port,
or send test data to a PDA (Personal Digital Assistant) for data
analysis. It is the best choice for interfacial tension of oils
against water determination.
