Máy đo tổn thất điện môi STD-A
Giới thiệu
Dielectric loss and dielectric constant are important physical properties of various ceramic such as electro ceramics,ceramic for mounting purposes,capacitor etc. The instrument is used in determining dielectric loss angle tangent tan δ and dielectric constant (e) to know more about various factors that effect the dielectric loss and dielectric constant, and to provide basis for improving the properties of materials. It is widely used in application study of properties of inorganic nonmetal new materials of institutions of higher education and research institutions. The instrument is in line with the standard of GB/T5594.4-1985.
