Sunshine SS-024 Precision Multimeter Pen For Multimeter Voltage Check Multimeter Probe

The Sunshine SS-024 Precision Multimeter Pen is a professional-grade test lead engineered for technicians, engineers, and electronics enthusiasts who demand unparalleled accuracy, durability, and safety in electrical measurements. Designed to meet the rigorous standards of modern diagnostic work, this multimeter probe combines cutting-edge materials, ergonomic design, and universal compatibility to deliver reliable performance across a wide range of applications—from circuit board repairs and automotive diagnostics to industrial maintenance and laboratory testing.

Crafted with 20A extra-point type reinforced alloy steel probes, the SS-024 features lengthened 22mm needle tips with a precise φ2mm diameter, ensuring deep penetration into tight spaces and accurate contact with micro-components. The high-precision, anti-oxidation gold-plated tips minimize contact resistance, enhance conductivity, and prevent corrosion even after prolonged exposure to harsh environments. Whether you're probing SMD components, IC pins, or automotive wiring harnesses, the SS-024 guarantees minimal measurement error and maximum signal integrity.

The full length of 1100mm (with a 970mm conductor) provides ample reach without compromising flexibility. The lead is constructed using 42×0.1 ultra-fine oxygen-free copper cores wrapped in dual-layer rubber-insulated PVC sheathing, offering exceptional tensile strength, folding resistance, and knot-free operation. This robust construction ensures the cable remains flexible in extreme temperatures—from freezing conditions to high-heat environments—making it ideal for field technicians working in diverse climates.

Safety is paramount in high-voltage testing. The SS-024 is rated CAT III 1000V / 20A, compliant with international safety standards, and features double-insulated silicone-grade PVC casing that prevents electrical leakage and shields against interference. The soft injection-molded connection joints eliminate stress points, significantly extending service life and preventing wire breakage during repeated flexing.

Ergonomically designed with a non-slip textured PVC handle, the probe ensures secure grip even with gloved hands or in humid conditions. The universal 4mm banana plug with dust-proof sealing caps fits seamlessly into virtually all standard digital and analog multimeters, including Fluke, UNI-T, Mastech, and other leading brands. No adapters needed—just plug, test, and trust.

Advanced Engineering Features

1. Gold-Plated High-Precision Tips

The needle tips are electroplated with pure gold, reducing contact resistance to near zero and ensuring stable readings even at microamp levels. This feature is critical when measuring low-voltage signals in sensitive circuits such as smartphones, drones, and medical devices.

2. Extended 22mm Reinforced Probe

Unlike standard 16–18mm probes, the 22mm length allows deeper access into multi-layer PCBs, connector sockets, and crowded wire bundles without bending or breaking. The 2mm diameter alloy steel core maintains structural rigidity under pressure.

3. Dual-Layer Insulated Ultra-Soft Cable

The conductor is encased in two protective layers:

• Inner silicone rubber core – enhances flexibility and thermal stability
• Outer PVC jacket – provides mechanical strength and abrasion resistance

This combination enables faster signal transmission, lower capacitance, and reduced noise interference.

4. Soft Injection-Molded Stress Relief

The transition zone between cable and plug is injection-molded with flexible TPE, distributing bending stress evenly and preventing fractures—a common failure point in low-quality leads.

5. Dust-Proof Banana Plug Caps

Each plug includes a removable protective cap, preventing dust ingress and maintaining electrical integrity during storage or transport.

Ideal for:

• SMT/SMD soldering inspection
• Automotive ECU & sensor testing
• Telecom & network equipment diagnostics
• Consumer electronics repair (phones, laptops, TVs)
• Industrial control systems maintenance
• Educational labs and R&D prototyping
