FNIRSI LC1020E High-Precision Handheld LCR Meter is a portable and intelligent tool for testing electronic components, ideal for engineers, technicians, and hobbyists. It supports L/Q, C/D, and R/D measurements with series/parallel models, and features a 2.8-inch TFT color display.

With preset thresholds and audio-visual alerts, it enables fast pass/fail judgments, improving batch testing and quality control. Supporting up to 100 kHz test frequency, it handles high-frequency analysis of inductors, capacitors, and resistors. Its compact, battery-powered design allows precise, cable-free measurements anytime, anywhere.

Features:

• High-Precision Measurement with 4.5-Digit Resolution
• Achieves up to ±0.05% basic accuracy, offering 10× improved precision for professional-grade measurements.
• Wide Parameter Support
• Measures L/C/R/Z values with automatic mode switching, and displays X/D/Q/θ/ESR as secondary parameters for comprehensive component analysis.
• Smart Auto Component Identification
• Automatically recognizes R/L/C components and switches modes instantly — ensuring fast and efficient testing with minimal manual input.
• Multi-Frequency & Test Voltage Selection
• Supports 5 test frequencies: 100Hz, 120Hz, 1kHz, 10kHz, 100kHz
