The FNIRSI LCR-ST2 is a smart tweezer-style meter that measures resistance, capacitance, inductance and diodes on small electronic components.
The tweezer design makes it easy to test SMD (surface mount) parts that are too small for standard meter probes.
What Does It Measure?
Resistance: 10mΩ to 10MΩ
Capacitance: 1pF to 22mF
Inductance: 1µH to 10H
Diodes: forward voltage detection
Voltage: up to 30V DC
Auto recognition detects whether you’re measuring a resistor, capacitor or inductor.
No need to switch modes manually for basic component testing.
Why Tweezer Style?
SMD components are tiny.
Standard multimeter probes struggle to make good contact.
The LCR-ST2 tweezer tips grip small parts securely for accurate readings.
Ideal for testing components on boards or sorting loose parts from reels and trays.
Colour Display
The 1.47-inch high-definition colour screen shows clear readings.
Dual-mode display shows two measurements on screen at once for direct comparison.
Adjustable brightness suits different lighting conditions.
Five Test Frequencies
The LCR-ST2 offers five test frequencies: 100Hz, 120Hz, 1kHz, 10kHz and 100kHz.
Different frequencies suit different component types and values.
The sweep function scans across all frequencies with a single press.
Get multi-frequency data quickly for accurate component analysis.
Intelligent Sorting
The automatic sorting function classifies components during batch testing.
Useful when checking component reels or sorting mixed parts.
Speeds up quality checks and inventory work.
Portable and Rechargeable
Built-in 300mAh lithium battery.
Runs for approximately three hours on a single charge.
Compact tweezer design fits in your pocket or toolkit.
Magnetic attachment keeps the device secure when not in use.
