5V To 90V Car Tester Pen Voltage Circuit Test DC Digital Display Electric Pen Probe Pen Auto Diagnostic Tools 6V 12V 24V 48V

【2 Color LED & Digital Display】The Power Circuit Probe Kit designed with LED digital voltage display for accurate volt readouts. Bidirectional current voltage testing mode, you can attach the alligator clamp either to negative or positive ground, red light indicates positive polarity and green light indicates negative polarity. Compared with LCD, LED lights are not affected by light brightness, and can be read accurately in daytime or dark areas.

【COMPUTER SAFE】Equipped with insulation protective cover,which can better grip the body and screws, insulation protection against electric shock. Circuit board with line protection function, safer and more burn-resistant.

【FLEXIBLE TO USE & CARRY】Extra long PU spring wire increases flexibility, range, and freedom when testing. A sharp stainless steel probe with protective rubber tip can reach into tight places and pierce insulation. Compared to cable wires, coil spring wires are lighter and easier to carry. This does not need to take up too much space in your toolbox or any storage area, it is convenient to use anytime, anywhere.

【WIDELY USE】This Professional automotive heavy duty circuit test light designed to test 5-90V DC voltage. Can be used to detect power, ground and find shorts and breaks in wires. Quickly check automotive headlights, taillights, turn signal circuits, faulty sockets, connections, fuses, broken wires and more.

We recommend choosing a 5V-70V voltage detection pen.
This product adopts a constant current source mode, with a wide detection voltage range and will not be damaged due to incorrect operation.
Some trucks have a power supply exceeding 48V, which is fully capable of helping you easily complete the inspection.

Chip upgrade, working range 5V -90V
Due to the possible presence of an oxide layer on the surface of the wiring terminal you are measuring, this can cause measurement errors, which are less than ± 1.5V.
Thank you very much for your order

The tail of the test pen has two different structures, as shown in the following figure, which have the same function of preventing wire breakage.
Because we have a large number of orders, we will randomly select one and the user cannot specify it.
They are all reliable and durable.
Thank you for your understanding.
