The Amprobe LCR55A is a versatile handheld component tester that measures inductance, capacitance, resistance, and tests transistors, diodes, and microwave diodes. Its wide range of functions makes it an indispensable tool for technicians.

Resistance measurement spans 20Ω to 20MΩ with up to ±0.5% accuracy, while capacitance covers 200pF to 2000μF with ±1.0% accuracy. Inductance ranges from 200μH to 200H with ±3.0% accuracy. The tester features a built-in transistor hFE test (0–1000), diode test, and audible continuity. An oversized digital display, Data Hold, Max Hold, and Zero Adjust potentiometer for ohms enhance usability.

With overload protection, low battery indicator, and auto-off power function, the LCR55A delivers reliable component analysis. It ships with test leads, alligator clips, spare fuse, and battery, ready for immediate use.
