Key benefits Nondestructive cable access: the needle is extremely thin and hard stainless steel, allowing it to prick the cable sheath without splitting it. This enables safe probing during testing. Accurate, durable probing: antibreakage soft handles and copper needles provide higher sensitivity and easier manipulation during tests, with durable materials for reliable use. Versatile compatibility: designed to be compatible with banana plugs and post ties, offering convenience and flexibility for multimeter setups. Broad applicability: suitable for auto maintenance, telecom testing, constructionsite testing, and other cable nondestructive testing scenarios. What this kit offers Thin and hard stainless steel needle for precise, gentle penetration of cable sheaths without damage. Antibreakage soft handles paired with copper needles to improve control and responsiveness during testing. Durable materials engineered for repeated use in professional testing environments. Compatibility with banana plugs and post ties to integrate easily with standard multimeter equipment. Typical use scenarios Auto maintenance: access signal lines or conduct quick, nondestructive tests on vehicle wiring harnesses. Telecommunication testing: probe internal conductors in telecom cables without cutting insulation. Construction site testing: perform field cable checks and nondestructive testing on installed systems. General cable testing: use in any situation requiring nondestructive probing with a multimeter setup.
