Profile:


The intermolecular forces form the interfacial tension or surface tension of a liquid, and the magnitude of the tension value can reflect the physical and chemical properties of the liquid and its material composition. It is one of the important indicators for evaluating product quality in related industries. The fully automatic tension tester produced by our company complies with the GB/T6541 standard and is based on the ring method (platinum ring method) to measure the surface tension (liquid gas phase interface) and interfacial tension (liquid-liquid phase interface) of various liquids. This method is widely used due to its advantages of simple operation and high accuracy. Widely used in industries such as electricity, petroleum, chemical, pharmaceutical, food, and education.
