Dielectric loss and dielectric constant is an important physical property of various metal oxides, plates, porcelain (pottery), mica, glass, plastics and other substances.

The factors affecting the dielectric loss and dielectric constant can be further understood through the measurement, which provides a basis for improving the properties of materials.

The instrument is used in research institutions, schools, factories and other units for the application of inorganic metal properties of new materials.
