Penna elettronica digitale per auto, tester per circuiti auto 6V-12V-24V DC, lampada di prova con cavo a molla esteso da 1,8 metri

🚘 Special design: Thanks to the integrated design of the probe's protective cap, a needle protection function has been added to prevent puncture wounds and loss of protection. Convenient to carry and take anywhere.

🚘 Function: The circuit probe set is designed with a digital LCD voltage display for accurate voltage measurements. Measurements can be performed accurately both during the day and in dark spaces. The sharp stainless steel probe effortlessly pierces wires, even in hard-to-reach places. The insulating rubber tip protects against electric shocks.

🚘 Safe and durable for computers: The professional automotive circuit tester features a built-in chip on the circuit board, which is safer and more durable than traditional test lamps and prevents the car's computer circuit board from burning out. Thanks to the wire's anti-bend design, you don't have to worry about poor contact with the line.

🚘 Universal Fit: This professional automotive circuit test lamp is designed to test 6V-12V-24V DC voltage. It can be used to detect current and ground, and to locate short circuits and breaks in wires. Quickly check car headlights, taillights, turn signal circuits, faulty sockets, connections, fuses, broken wires, and more.

🚘 User-Friendly: The 1.8-meter extra-long PU spring wire increases flexibility, reach, and freedom during testing. A sharp stainless steel probe with a protective rubber tip can reach into tight spaces and pierce insulation. Compared to cable wires, spiral spring wires are lighter and easier to carry. This does not need to take up much space in your toolbox or storage; it is convenient to use anytime and anywhere.

🚘 Testing procedures: Attach the parts to be tested, connect the alligator clip of the test probe to the negative or positive ground, and use the probe to make contact with the other side. There is a bidirectional LED on the circuit board for polarity indication, where a red light indicates positive polarity and a green light indicates negative polarity. After completing the above steps, the circuit board clearly displays the digital voltage value of the LED.
