Instrumentation

This inductance measurement bridge is designed for precise determination of unknown inductances using a comparison method against standard variable inductance or capacitance. Equipped with an internal 1 kHz sine wave generator, it provides stable excitation for accurate bridge balancing. The onboard null detection system—featuring either a digital panel meter or voltmeter—allows users to identify exact balance conditions with high accuracy. With a typical inductance measurement range from 15 mH to 200 mH and optional resistance measurement capability from 5 Ω to 100 kΩ, this instrument is widely used in laboratories, educational institutions, and R&D environments requiring reliable AC bridge measurements.
