FNIRSI LCR-ST1 – Digital SMD Tweezer Tester with Smart LCR Measurement

Compact LCR meter with component identification and data logging

The FNIRSI LCR-ST1 is a mini multifunctional SMD tester that measures resistance, capacitance, inductance, diodes, ESR, and more. It supports 3 test frequencies (100 Hz / 1 kHz / 10 kHz) and automatically identifies components while displaying real-time parameters like Q, D, X, and Z on a high-resolution 1.14" screen. Designed with interchangeable gold-plated tweezer tips (straight and curved), a magnetic back, and a rechargeable 250 mAh battery via USB-C – ideal for engineers, students, and repair technicians.
