Product Overview

Elevate your electrical diagnostics with our High-End Test Pen with Lighting — a premium-grade testing instrument engineered for electricians, maintenance technicians, and industrial professionals who demand accuracy, speed, and reliability. Featuring a precision contact head, a luminous digital display, a high-sensitivity induction electrode, and a built-in floodlight with indicator light, this test pen delivers unmatched performance in any lighting condition. Housed in a rugged engineering plastic shell, it combines professional-grade durability with intuitive operation — making it the ultimate companion for live circuit testing, troubleshooting, and electrical safety verification.

Key Features & Benefits

Precision Contact Head – Direct & Accurate Measurements

The test pen is equipped with a high-quality metal contact head designed for direct, stable contact with live circuits. This ensures accurate voltage and current readings without signal interference or false readings — critical for reliable diagnostics on sensitive electronic systems, control panels, and power distribution equipment.

Luminous Digital Display – Clear Visibility in Any Light

The built-in digital LCD screen features a luminous (backlit) display, ensuring crystal-clear readability even in dark basements, engine bays, nighttime job sites, or poorly lit cabinets. No more squinting or guessing — just instant, precise numerical feedback at a glance.

Induction Electrode – Quick & Efficient Non-Contact Testing

In addition to the contact head, this test pen features a built-in induction (non-contact) electrode that detects the presence of AC voltage without touching the wire. This allows for rapid, safe preliminary scanning of circuits — helping you identify live wires faster and avoid dangerous contact before performing detailed measurements.

Durable Engineering Plastic Shell – Built to Last

The entire body is constructed from high-impact engineering plastic (ABS+PC blend), providing exceptional resistance to drops, impacts, chemicals, and electrical insulation. This rugged housing protects the internal electronics from job-site abuse while keeping the tool lightweight and comfortable for all-day use.

Floodlight & Indicator Light – Enhanced Illumination for Precision Work

A powerful built-in LED floodlight illuminates the work area, while a dedicated indicator light signals test status (live/neutral/ground). This dual-lighting system ensures you can see exactly what you're testing — even in complete darkness — dramatically improving accuracy, safety, and efficiency during night shifts, underground work, or confined-space repairs.
