Why Professionals Choose This Kit
- Accurate measurements: Nickel-plated jaws and gold-plated contacts reduce contact resistance and voltage drop for reliable readings.
- Fast identification: The 5-color system eliminates guesswork when tracing signals and powering prototypes.
- Durable design: Serrated teeth and strong springs hold components securely—ideal for repeated bench use.
- Safe to use: Double insulation lowers the risk of accidental shorts; rated for typical electronics and low-voltage automotive tasks (up to 5 A).
- Tidy storage: Anti-snag design and color coding keep sets organized for classrooms and labs.
Common Applications
- Electronics repair and diagnostics — clip to component leads, pins and headers quickly.
- Arduino & Raspberry Pi prototyping — fast temporary connections for sensors and modules.
- PCB prototyping — hold test points and components securely during bench testing.
- STEM education — robust for classroom demonstrations and student labs.
- Automotive electrical troubleshooting — safe for low-current tests on wiring harnesses and accessories.
FAQ
Are these leads suitable for multimeter probes?
Yes — the clips attach cleanly to component leads and test points. For precision metering, ensure contact surfaces are clean and use the gold-plated contacts where available.
Can I use them for 12V automotive systems?
Yes — they're rated up to 5 A and are safe for many low-current automotive accessories. Avoid high-current starter or charging system tests that require heavier gauge wiring.
How should I store the set to avoid tangles?
Coil leads loosely and secure with cable ties or use a small parts organizer. Store colors grouped together to speed selection.
