GD-6541A Digital Interfacial Tension Meter Transformer Oil Surface Tension Testing Equipment ASTM D971
Introduction:
Surface Tension Tester 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 instrument 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 instrument 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.
