Dielectric constant tester

Meet the standard: GBT 1409-2006 Recommended method for measuring the permittivity and dielectric loss factor of electrical insulation materials at power frequency, audio frequency, and high frequency (including meter wave wavelength)

1 Overview

Dielectric loss and dielectric constant are important physical properties of various ceramics such as electrical ceramics, device ceramics, capacitors, and composite materials. By measuring the dielectric loss tangent tan δ and dielectric constant (ε), various factors affecting dielectric loss and dielectric constant can be further understood, providing a basis for improving material performance; The basic principle of the instrument is to use high-frequency resonance method and provide universal, multi-purpose, and multi range impedance testing. It uses a single-chip computer as the control of the instrument, and the measurement core adopts new technologies such as frequency digital locking, automatic setting of standard frequency test points, automatic search for resonance points, automatic conversion of Q value range, numerical display, etc. It improves the tuning circuit, reduces the residual inductance of the tuning test circuit to the lowest level, and retains the automatic amplitude stabilization technology in the original Q meter, making the new instrument more convenient to use and more accurate in measuring values. The instrument can measure the Q value of high-frequency inductors or resonant circuits, the inductance and distributed capacitance of inductors, the capacitance and loss tangent of capacitors, the high-frequency dielectric loss of electrical materials, the effective parallel and series resistance of high-frequency circuits, and the characteristic impedance of transmission lines under high testing frequency conditions.

This instrument is used for applied research on the properties of inorganic non-metallic new materials in scientific research institutions, schools, factories, and other units.
