Dielectric Constant Tester
The STD-A measures dielectric loss tangent (tanδ), dielectric constant (ε), inductance, capacitance, and Q-value using a high-frequency resonance method with multi-range impedance measurement, with reference to GB/T 5594.4-1985. It is intended for electrical ceramics, device ceramics, capacitor ceramics, composite materials, and other inorganic nonmetallic materials in research, teaching, and industrial laboratories.

Product Description
The STD-A uses a high-frequency resonance method and general-purpose impedance measurement over multiple ranges for dielectric loss tangent, dielectric constant, inductance, capacitance, and Q-value. It is used in research institutions, schools, and factories studying electrical ceramics, device ceramics, capacitor ceramics, composite materials, and other inorganic nonmetallic materials.
Q-value measurement covers 5–999 with selectable ranges of 30, 100, 300, and 999 and automatic range switching. A Q-value threshold can be preset over 5–999.
This page is a configuration overview. Obtain a verified STD-A datasheet defining the dielectric-loss-tangent range and accuracy, frequency-band assignment, capacitance measurement above 460 pF, and the applicable Q-value and frequency-error bases before technical selection.
