⚡ Still Guessing Which Wire Is Live?

Every electrician — pro or DIY — has been there: staring at a tangle of wires, unsure which one will shock you. One wrong touch and the consequences can be serious. There's a smarter, safer way.

🔍 Detect Live Wires Instantly — No Contact Needed

Our Responsive Electrical Tester Pen uses automatic induction technology to sense voltage through insulation, plastic shells, and wire coatings — without ever touching a bare conductor. Simply bring the tip close to a wire: if the bright LED lights up, the line is live. The brighter the glow, the higher the voltage. It's that intuitive.

🛡️ Built for Safety. Built to Last.

Crafted from drop-proof ABS insulation and hardened 45 steel, this pen is engineered to survive the job site — not just the toolbox. Whether you're troubleshooting a rice cooker, a computer, or a circuit breaker panel, it delivers reliable readings every single time.

✅ Key Features at a Glance

• 🔒 Safe & High-Quality Materials — Drop-proof insulation, ABS body, 45 steel tip for long-term durability
• 🔦 Bright LED Indicator — Clearly visible even in daylight; brighter light = higher voltage
• 📡 Non-Contact Induction — Detects live wires through insulation without direct contact
• 🔎 Breakpoint Finder — Trace wire faults in appliances like plug boards, computers & rice cookers
• 🔋 DC Battery Detection — Test battery charge level with a simple two-hand technique
• ✔️ Self-Check Function — Verify the pen is working before every use in seconds

🧠 How to Use — Quick Guide

Self-Check: Hold the pen tip with one hand and touch the tail with the other. Light on = pen is working and battery is good.

Live Wire Detection: Bring the tip close to the wire's insulation. Light on = live circuit. No contact required.

Find Breakpoints: Touch the bottom of the pen with one hand, run the tip along the wire. The point where the light goes out is the breakpoint.

DC Battery Test: Touch the pen tip to the positive terminal, touch the negative terminal with your other hand. Light on = battery charged.

⚠️ Good to Know

• Always ensure your hand is touching the metal screw rod at the bottom of the pen — otherwise the circuit won't complete and readings will be inaccurate.
• The pen will light up on a live socket, but not on a ground/earth socket — this is normal behavior.
• Ambient static electricity may cause a faint flicker — this is not a fault.
