SH107 Automatic Interfacial Tensiometer SH107 Automatic Interfacial Tensiometer is developed and manufactured in accordance with GB/T6514. Using the ring method, it can determine the surface tension of various liquids at the liquid-gas interface and the interfacial tension between mineral oil and water at the liquid-liquid interface under non-equilibrium conditions. Built with microprocessor control, this instrument features high automation and stable performance for
