Insulation Testing: The clip set can connect to insulated wires without removing insulation, enabling safe and quick testing in car electrical circuits, with a multimeter or voltage tester, and for spot detection tasks. Non-Breaking Puncture Probe: A set of car wire probe clips and detection pins. The red and black color coded barrels provide quick circuit identification. Portable Size: Dimensions are 0.6 cm by 1.93 cm, and they fit for most plug-in probe pens. Durable Material: Puncture probe clips are made of strong, wear-resistant material, with adjustable detection size. Use scenarios: - Automotive diagnostics: probe car wiring harnesses and test circuits without stripping insulation. - General electronics testing: use with a multimeter or voltage tester for quick circuit checks. - Spot detection tasks: identify and verify voltages at specific points in wiring or panels.
