FNIRSI LC1020E High Precision LCR ESR Tester With Battery

FNIRSI LC1020E High-Precision LCR ESR Tester is a compact, handheld instrument designed for engineers, technicians, and electronics enthusiasts who need accurate component measurements on the go. With a basic accuracy of 0.3%, it delivers reliable L (0–100 H), C (0–100 mF), and R (0–10 MΩ) readings across multiple test frequencies, from routine checks to high-frequency analysis. The 2.8-inch TFT color display presents main and secondary parameters clearly, while the built-in 3.7V, 3000mAh battery and USB-C interface keep you productive away from the bench. Calibrate with open-circuit and short-circuit modes, enable data logging, and use the preset thresholds to quickly sort good and bad components with audible and visual prompts for batch testing efficiency. Its versatile three-terminal and five-terminal test configurations, plus five selectable test frequencies (100 Hz, 120 Hz, 1 kHz, 10 kHz, 100 kHz) and three test levels (0.1 V, 0.3 V, 0.6 V), cover a wide range of applications from lab work to production lines and on-site maintenance. It also supports fast measurement speed options to suit different testing scenarios.

Benefits & Tips

• Use the preset threshold values to quickly determine good/bad components, with audio and visual prompts to speed up batch testing.
• Take measurements on the go with the compact LC1020E and its long-lasting 3.7V 3000mAh battery—no cables required for everyday checks.
• Leverage the three-terminal and five-terminal configurations and selectable frequencies (100 Hz–100 kHz) to get accurate results for inductors, capacitors, and resistors in a variety of conditions.
