GH-8000E Dielectric Loss Tester is used for on-site anti-interference dielectric loss measurement, or precise dielectric loss measurement in laboratories. The instrument features an integrated structure, incorporating a dielectric loss bridge, variable frequency power supply, test transformer, and standard capacitor. It adopts variable frequency anti-interference and Fourier transform digital filtering technology, with fully automatic intelligent measurement, ensuring very stable measurement data under strong interference. Measurement results are displayed on a large screen LCD, and a built-in micro printer can print output.
