1、 Overview:

The JYW-200D fully automatic interfacial tension meter is a simple and practical testing instrument that uses physical methods instead of chemical methods. The machine adopts microcontroller technology, which is easy to operate and highly intelligent; It has functions such as automatic zeroing, real-time display of force values and curves, and peak holding; Automatic calculation, display, copying, and printing of test results; It can quickly and accurately measure the surface and interfacial tension values of various liquids. Used in the water and electricity department to test the interfacial tension value of electrical oil, in order to strengthen the supervision of insulation oil quality. In departments such as petroleum, chemical, and scientific research, surface tension values of various liquids can be tested to enhance the analysis of various liquids. For education departments, it can be used in teaching.
