YS-200B Automatic Interface Tensiometer is a kind of testing instrument that replaces chemical methods with physical methods. The automatic interface tension meter can quickly and accurately measure the surface and interface tension values of various liquids, and the results are automatically displayed. It is used in the hydropower sector to test the interfacial tension value of oil used in the electrical industry to strengthen the supervision of insulating oil quality. In petroleum, chemical industry, scientific research and other departments, the surface and interfacial tension values of various liquids can be tested to strengthen the analysis of various liquids. For the education sector, it can be used in teaching. 【Relevant Standards】

The instrument complies with the national standard GB5549 surfactant to determine the surface tension of the liquid film by pulling up the liquid film method, the international standard ISO304 “Surfactant – Determination of liquid surface tension by the pull-up liquid film method”, and the technical conditions of the interfacial tension meter JBT9388 the machinery industry standard. In line with the national standard GB/T18396 natural latex ring method for determination of surface tension meter, in line with the national standard GB11278 determination of critical micelle concentration of anionic and nonionic surfactants, and circular determination surface method.
