Digital display voltage: The car voltage tester can quickly and accurately display the voltage value. Easy to read. Measuring range: 3-48V DC, accuracy: 0.1V.
The positive and negative poles can be distinguished: the car voltage tester has built-in LED lamp beads, red indicates the positive pole, and green indicates the negative pole. Note: The negative pole will not display the voltage value.
Wide range of uses: The car voltage tester can be used for polarity detection, voltage testing, fuse detection, short circuit tracking and positioning, etc. It is very suitable for quickly checking car headlights, taillights, turn signal circuits, fuse connections, etc.
Spring wire + alligator clip design: The car circuit test pen is equipped with an alligator clip and a spring wire, which can be up to 1.5 meters long, making it easier for you to do more circuit tests.
High-quality materials: The handle of the current tester pen is made of high-quality AS, and the probe is made of carbon steel with chrome plated surface. The internal wires are made of copper wire.
