LCR ESR Meter FNIRSI LCR-ST2 2-in-1 Tweezers/Kelvin — Standard / Plus

LCR ESR Meter FNIRSI LCR-ST2 2-in-1 Tweezers/Kelvin — Standard / Plus

Compact 100 kHz LCR & ESR meter with tweezers mode, Kelvin 4-wire testing and 100 Hz–100 kHz sweep

The FNIRSI LCR-ST2 is a professional dual-mode LCR meter designed for precise testing of electronic components. It combines tweezer-based SMD measurement with Kelvin 4-wire testing (Plus version) for large and high-accuracy components. It measures R/C/L, ESR, D/Q/Z/X/θ, diodes and up to ±30 V, offering five test frequencies and full-band sweep.

With intelligent auto-recognition, tolerance grading, a bright 1.47" HD display, magnetic body and a 300 mAh battery, the LCR-ST2 is ideal for lab diagnostics, on-site service work and component verification.
