Voltcraft LCR-300 Digitale LCR-meter CAT I 20000 Counts

The Voltcraft LCR-300 stands out from typical handheld meters with its five test frequencies up to 100 kHz, enabling accurate component analysis across a broad range of applications. Unlike basic LCR meters that only measure at a single frequency, this instrument lets you evaluate inductors, capacitors, and resistors under conditions closer to real-world operating frequencies, revealing parameters that other devices miss.

Highlights

• Measures inductance, capacitance, resistance, dissipation factor, and quality factor
• Five selectable test frequencies: 100 Hz, 120 Hz, 1 kHz, 10 kHz, 100 kHz
• 20,000-count backlit LCD for clear readings in any light
• Auto-ranging with data hold and relative measurement functions
• CAT I 600 V safety rating for component-level testing
• Powered by a single 9 V block battery, with automatic power-off

In daily use

Whether you are sorting components, verifying capacitor ESR, or matching inductors for filter design, the LCR-300 delivers dependable results. The relative mode lets you zero out test lead resistance or stray capacitance, while the data hold function freezes readings for easy recording. The backlit display and intuitive controls make it comfortable to use on the bench or in the field, and the auto power-off preserves battery life during long sessions.
