Stainless Steel Circuit Tester with LED Display

High-Quality Probe Protection Cover

Adopt an integrated structure design that adds a needle guard function to ensure no stab wounds and prevents the guard from being lost. This design makes it convenient to carry and take wherever you go.

Accurate Voltage Measurement

The power circuit probe kit features an LCD digital voltage display, allowing accurate voltage readings both during the day and in dark areas. Equipped with a sharp stainless steel probe, it pierces wires effortlessly and reaches tight areas without difficulty. The protective rubber tip ensures safety against electric shock.

Easy-to-Use Design

The 140-inch long PU spring wire provides more flexibility, making it lighter and more durable than standard cable wires. The large size alligator clip simplifies one-hand operation, ensuring easy use and storage.

High-Visibility Display Screen

The high-visibility display screen indicates the circuit's signal, with the digital screen reflecting different measured voltages. This ensures clear and precise readings.

Versatile Applications

This DIY automotive circuit tester and circuit test light covers a 3-48V DC voltage range, making it ideal for car fuse testing, electric frequency voltage tests, circuit pole discrimination, car headlight, tail light, turn signal circuits, and faulty socket checks. Its multi-functional design makes this test pen practical and versatile.
