Inter-molecular forces

Type: ZC-214
      Intermolecular forces produce interfacial tension and surface tension of the liquid. The tension value reflects the physicochemical properties of the liquid sample and is one of the important indicators for measuring the quality of the product. The modified transformer tester ZC-214 automatic tension testing machine uses the ring method to test various liquid surface tensions and interfacial tensions. The method is simple and accurate. Widely used in electric power, petroleum, chemical, pharmaceutical, food, teaching and other fields.
