INGCO AC 100V–500V Professional Electrical Test Pencil (3x140mm)
Ensure absolute electrical safety before you touch any wire. The INGCO HSDT1408 Test Pencil is a highly reliable line voltage tester engineered to detect active electrical currents between 100V and 500V AC. Built with a high-visibility internal neon indicator bulb and a premium insulated body, this pocket-sized tool instantly tells you whether a terminal is safe to work on or live with dangerous voltage.
Safety Rating & Voltage Detection
- AC 100V–500V Testing Range: Universally optimized for standard Indian domestic and commercial power supplies. It safely and accurately identifies live lines across 230V single-phase outlets, distribution panels, and appliance terminal blocks.
- High-Visibility Neon Glow Tube: Features a premium neon lamp sealed inside the clear handle. The moment the metal tip contacts a live wire and you touch the metal top cap, the bulb glows brightly, giving you an instant visual confirmation even in well-lit rooms.
- Integrated Safety Resistor: Engineered with a built-in, high-resistance safety carbon element that drops the voltage down to a completely imperceptible micro-current, keeping the operator 100% safe from electric shocks while testing.
Precision Blade & Compact Build
- Slim 3mm Slotted Tip: The tester features a high-grade 3mm wide by 140mm long slotted (flathead) blade. This slim, elongated profile is specifically designed to slide effortlessly into deep-set modular wall sockets and tight terminal blocks.
- Fully Insulated Crystal Handle: Molded from high-tensile, crystal-clear insulating resin that provides maximum electrical isolation while allowing you to view the neon indicator clearly from any angle.
- Sturdy Pocket Clip: Features an integrated metal pocket clip on top, allowing you to carry it securely in your shirt pocket or tool pouch for rapid, one-handed access on-site.
Product Specifications:

Best Use Cases
- Domestic Electrical Maintenance: The absolute must-have pocket tool for checking wall sockets, ceiling fan connections, and modular light switches before replacing fixtures.
- Industrial Panel Diagnostics: Ideal for maintenance staff and electricians rapidly cross-checking live fuses, circuit breakers, and control terminal rails in distribution boards.
- Appliance Troubleshooting: Perfect for identifying grounding faults or current leakages on the metal bodies of refrigerators, washing machines, and water heaters.
TK Pro Tip: Always verify your test pencil on a known live source before trusting it on an unknown wire! Before testing a dead circuit, place the tip into a live, working wall socket first to confirm that the internal neon bulb lights up perfectly. When testing, ensure your finger makes solid contact with the metal ground button on the very top of the handle to complete the circuit safely!
