STD-A Dielectric Constant Measuring Instrument Permittivity Tester
Description
Dielectric loss and dielectric constant are important physical properties of various ceramics such as electrical porcelain, device porcelain, capacitors, and composite materials, etc. By measuring the dielectric loss tangent (tanδ) and dielectric constant (ε), one can further understand various factors affecting dielectric loss and dielectric constant, providing a basis for improving the performance of materials. The basic principle of the instrument is to adopt the high-frequency resonant method, and it provides a universal, multi-purpose, and multi-range impedance testing. It uses a single-chip computer as the instrument's control, with automatic conversion of Q value range, numerical display, and other new technologies. It improves the tuning circuit, reducing the residual inductance of the tuning test circuit to the minimum, and retains the automatic amplitude stabilization technology in the original Q meter, making the new instrument more convenient to use and the measurement values more accurate. The instrument can measure the Q value of high-frequency inductors or resonant circuits, the inductance and distributed capacitance of inductors, the capacitance and dielectric loss tangent value of capacitors, the high-frequency dielectric loss of electrical materials, the effective parallel and series resistances of high-frequency circuits, and the characteristic impedance of transmission lines under higher testing frequency conditions. This instrument is used by research institutions, schools, factories and other units for the application research on the performance of inorganic non-metallic new materials.
