Dielectric Constant Tester DZ5001 High Precision Digital Display Dielectric Loss Factor Tester
The Dielectric Constant Tester DZ5001 is a high-precision instrument specifically designed for measuring the dielectric constant and dielectric loss coefficient (loss tangent) of materials. This device adopts the high-frequency resonance method and is mainly applied in scientific research institutions, schools, factories, and other units for the applied research of new inorganic metal materials.
I. Core Performance Features
High-precision measurement with automatic deduction: The instrument can automatically deduct residual inductance and test lead inductance, greatly improving measurement accuracy. Among them, the dielectric loss coefficient accuracy can reach 1/10,000, and the dielectric constant accuracy can reach 1/1,000.
Direct measurement of large capacitance values: It has the function of directly measuring and displaying large capacitance values, with a maximum measurement value of up to 25nF, and is equipped with a digital micro-measurement device that supports direct reading.
High-frequency digital synthesized signal: It adopts a DDS digital synthesized signal source with a frequency range covering 10KHz to 100MHz, a frequency coverage ratio of 7000:1, and a signal frequency accuracy of 6 significant digits.
Automation and convenient operation: It supports automatic capacitance search (with stepper motor) and automatic resonance point scanning. The LCD screen can directly display various parameters such as F, L, C, Q, Er, making operation convenient.
High-stability sampling: It uses 12BIT high-precision AD sampling to ensure the stability of the Q value, performing particularly stably when testing low dielectric loss materials.
