Tweezer-style LCR ESR meter with 1.47 inch display and Kelvin clips

BFKK

BFKK LCR-ST2 100kHz LCR ESR Meter Tweezer car electronics accessory

SKU CH-KYB3-4Z9RB

Handheld tweezer meter tests SMD and through-hole resistors, capacitors, inductors, diodes, voltage and continuity with 100 kHz scan and auto sorting

  • Tests SMD and through-hole parts with tweezer probe
  • Auto-sorts components to flag abnormal readings
  • Five test frequencies from 100 Hz to 100 kHz
  • Four RMS voltage levels from .1 V to 1.0 V
  • 47 inch HD display with left or right-hand mode

All-in-One LCR/ESR Tweezer Meter

The BFKK LCR-ST2 is a handheld tester for SMD and through-hole components. It measures resistors, capacitors, inductors, diodes, voltage and continuity. Technicians and hobbyists use it for quick diagnostics and component verification on the bench or in the field.

100 kHz Full-Range Scan Capability

The meter scans at 100 Hz, 120 Hz, 1 kHz, 10 kHz and 100 kHz to cover RF parts up to large electrolytics. Four RMS test levels of .1, .3, .6 and 1.0 V with series and parallel modes reduce parasitic effects. Primary and secondary parameters display R, C, L, Z, X, D, Q and phase angle simultaneously.

Rechargeable Handheld Operation

A built-in 300 mAh battery charges via Type-C and supports auto power-off to extend runtime. The 1.47" HD display offers adjustable brightness and left or right-hand modes. A high-strength rear magnet secures the unit during sustained testing sessions while Kelvin clips and tweezer tips swap quickly.

Questions about this item

What does the 100 kHz test frequency actually let me measure on a real board?

The 100 kHz scan covers RF-range components down to 1 pF capacitors and up to 10 H inductors, so you can verify SMD parts and larger electrolytics in-circuit without desoldering.

How does the Type-C charging port limit daily use?

The built-in 300 mAh battery charges over Type-C and supports auto power-off, giving a full day of bench testing between charges with no proprietary cable needed.

What clearance do the tweezer tips and Kelvin clips need to fit onto a crowded PCB?

The quick-swap tweezer tips and Kelvin clips plug directly into the meter body, so only the probe ends touch the board — no extra module or cable bulk to clear tall components.
