JTC-6934 Taiwan Cordless Circuit Tester 3-30V DC Auto Electrical Test Pen

The JTC-6934 Cordless Circuit Tester is a professional automotive electrical testing tool designed for quickly identifying voltage polarity without the need for a ground lead or alligator clip.

Unlike conventional test lights, the JTC-6934 uses the operator's body as the ground reference, allowing fast and convenient testing of 3–30V DC automotive electrical circuits.

Equipped with dual-colour LED indicators and a dual-tone buzzer, it clearly distinguishes positive and negative polarity, making electrical diagnosis faster and easier.
