LCR-T4 Graphical Transistor Tester with Resistor, Capacitor, ESR, and SCR LCD Display

The LCR-T4 is a must-have diagnostic tool for electronics repair and DIY projects. It features a large 12864 graphical LCD that automatically identifies the component you plug in—whether it’s a transistor, MOSFET, diode, or resistor. Unlike basic meters, it provides a full schematic symbol on the screen and identifies the pinout (1-2-3) so you know exactly how to solder it. It is especially famous for its built-in ESR (Equivalent Series Resistance) meter, which allows you to check if electrolytic capacitors are actually healthy or failing internally. It operates on a standard 9V battery and features an auto-power-off function to save energy.

Features:

• Auto-Detection: Automatically identifies NPN/PNP transistors, N/P-channel MOSFETs, JFETs, diodes, and SCRs.
• Graphical Interface: Displays the component's circuit symbol and pin configuration (Emitter, Base, Collector, etc.).
• ESR Measurement: High-precision testing for capacitors over 2uF with a resolution of 0.01Ω.
• One-Button Testing: One click starts the test; the device shuts down automatically after showing results.
• Component Troubleshooting: Measures current gain (hFE) and gate threshold voltage for transistors and FETs.
• Backlit Display: Clear 128x64 LCD for easy reading in low-light environments.
