ASTM D971 Automatic Interfacial Tension Meter for Transformer Oil
The interaction force between molecules form the interfacial tension or surface tension of liquids. The size of tension value can reflect the physical and chemical properties of liquids and their material composition. It is one of the important indicators for related industries to investigate the quality of products. This product is suitable for GB/T6541 standard. Based on ring method (platinum ring method), the surface tension (liquid gas interface) and interfacial tension (liquid liquid interface) of various liquids are measured. This method has the advantages of simple operation and high accuracy and is widely used. It is widely used in power, petroleum, chemical, pharmaceutical, food, teaching and other industries.
