Transform the Way You Test Electronics

Are you tired of juggling bulky multimeter probes while trying to test microscopic SMD components? The FNIRSI LCR-ST2 is engineered to solve the frustration of modern electronics repair. It isn't just a tool; it's your pocket-sized diagnostic lab.

Precision Meets Versatility

Most portable testers fail at high frequencies. The LCR-ST2 breaks the mold with a professional 100Hz–100kHz frequency range and varying signal levels (up to 1.0V RMS). This ensures accurate "In-Circuit" testing for capacitors, inductors, and resistors, allowing you to measure ESR (Equivalent Series Resistance) with confidence—crucial for identifying bad capacitors in power supplies and motherboards.

Designed for the Workbench and the Field

What sets the ST2 apart is its unique 2-in-1 Modular Design. Use the precision gold-plated tweezer tips for tiny 0402/0603 SMDs, or instantly swap to the Kelvin Test Clips (included) for through-hole components and larger capacitors.

Work Smarter, Not Harder

• Intelligent Sorting: Set your tolerance (e.g., 1% or 5%) and quickly sort through a pile of mixed components. The device automatically buzzes to tell you if a part is a "Pass" or "Fail."
• Auto-Rotate Screen: Whether you are left-handed or right-handed, the 1.47" HD Color OLED display flips automatically to match your grip.
• Secondary Parameters: Don't just see the capacitance; see the Dissipation Factor (D), Quality Factor (Q), and Phase Angle ($\theta$) simultaneously.
