An automatic anti-interference precision tan delta measuring instrument is used for on-site anti induced voltage dielectric loss measurement or laboratory precision dielectric loss measurement. The instrument has an integrated structure with a built-in dielectric loss bridge, variable frequency power supply, test transformer, and standard capacitor. Using frequency conversion anti-interference and Fourier transform digital filtering technology, fully automatic intelligent measurement, the measurement data is very stable under strong interference. The measurement results are displayed on a large-screen LCD and can be printed out with a built-in micro printer. Contact us for quotation
