Description
Introduction:
The instrument adopts platinum ring method, under non-equilibrium conditions, automatic control using internal microcomputer, determination of all kinds of liquid surface tension (liquid - gas interface) and mineral oil-water interfacial tension (liquid - liquid interface);
After pouring sample into the sample cup, just press the start button, the instrument will automatically complete the determination of the sample, and it can automatically calculate the tension value according to the input parameters.
