The DT71 is a compact set of digital measuring tweezers that combines multifunction component measurement, a miniature waveform signal generator and fully differential input measurement in one portable tool.
Its three-section split design includes a controller, measuring arm and tweezer head that can be replaced and combined as needed. The 360° rotatable controller has a 96*16 OLED display, smart posture recognition for left and right operation, and a hidden touch button instead of physical front-panel buttons.
Use it in manual mode or automatic recognition mode to quickly identify SMD resistors, capacitors, inductors and diodes, while displaying primary and secondary parameters. It is suited to bench work, lab use, maintenance, component sorting and field troubleshooting.
Included in the package are a DT71 Controller x1, Test Arm x1, Tweezer Tip x2, Dedicated Data Cable x1, Carrying Case x1 and Safety Instructions x1.

Jargon buster
Plain-language definitions for the technical terms used above.
- Differential input
- A measurement method where the board reads the voltage difference between two input wires instead of measuring one wire compared with ground. This is useful for small sensor signals and noise reduction, but both input voltages still need to stay within the board’s allowed range.
- LED
- A light-emitting diode is a small electronic component that lights up when current flows through it in the correct direction. In this kit, LEDs create the flashing effect, so polarity and correct soldering matter for the project to work.
- OLED
- OLED stands for organic light-emitting diode, a display type where each pixel produces its own light. It matters because OLED screens are thin, high-contrast and easy to read for small status displays, but they can be more sensitive to image burn-in than some other display types.
