Designed to pierce wire insulation for electrical measurements without damaging the conductors, these acupuncture and moxibustion probes are suited for automotive diagnostics and electronics work. What’s included - Set of 5 probes - 20 spare pins for tip replacement, so you can restore performance without replacing the whole probe Key benefits - Non-destructive testing: pierce insulation to access the conductor for accurate electrical measurements - Replaceable tips: 20 spare pins allow continued use without discarding probes - Precise contact in tight spaces: very small diameter and fine needle tip optimize insulation penetration on small wires - Versatile for electronics work: suitable for use on small printed circuit boards when probing is required Design and performance - High-quality construction designed for durability in professional diagnostic and repair environments - Fine needle tips facilitate controlled and precise contact with insulated wires - Compatible with common measurement workflows in automotive and electronics testing Specific use scenarios - Automotive diagnostics: access insulated wires to monitor continuity, voltage, or resistance without stripping insulation - Small PCB probing: use as needle probes for testing signals on tight or delicate boards - Electronics prototyping and repair: precise insulation penetration in confined areas where traditional probes struggle This set provides a practical, durable solution for quick, non-destructive electrical measurement across automotive and electronics applications, with replaceable tips to extend tool life.
