FNIRSI DMC-100 Digital LCR Meter – High Precision Handheld Inductance, Capacitance, & Resistance Component Tester

Overview 

The FNIRSI DMC-100 Digital LCR Meter is a professional-grade, portable component testing instrument designed for hardware engineers, electronics repair technicians, and quality control labs. Unlike standard digital multimeters that offer basic capacitance readings, the DMC-100 delivers true LCR testing, measuring precise Inductance (L), Capacitance (C), Resistance (R), and quality factors (D/Q/ESR). Equipped with a vibrant HD color screen and an internal rechargeable lithium battery, this handheld tester makes component sorting, PCB troubleshooting, and SMD auditing fast and accurate.

Key Features 

• Comprehensive Component Testing: Accurately measures inductors, transformers, electrolytic/ceramic capacitors, resistors, and ESR (Equivalent Series Resistance).

• HD Color Display Screen: High-resolution display clearly shows primary parameters along with secondary metrics (D (Dissipation Factor),Q (Quality Factor), ESR (Resistance), θ(Phase Angle)).

• Multiple Test Frequencies: Supports selectable test signal frequencies (100Hz, 1kHz, 10kHz) for precise frequency-dependent component evaluation.

• USB-C Rechargeable: Built-in lithium battery recharges quickly via standard USB-C, eliminating the need for disposable 9V batteries.

• Kelvin Test Clips Included: Supplied with high-quality Kelvin test leads to eliminate lead resistance errors during low-value component testing.

Popular Bench Applications 

• SMD & Through-Hole Component Auditing: Sort unknown, unlabeled, or salvaged inductors and capacitors before soldering onto custom PCBs.

• Power Supply Troubleshooting: Measure ESR on filtering electrolytic capacitors to detect failing or swollen caps before total board failure.

• Transformer & Coil Winding: Verify custom inductor coil values for buck/boost converters and radio frequency circuits.
