Voltage Tester Screwdriver, Non Contact Voltage Detector Pen with LED, Electrical Test Screwdriver
-
No more guessing at the breaker: touch the cap to see if a wire is hot, neutral, or dead
-
Works without touching the wire: hold it near any wire and the light confirms voltage is present
-
Find the break fast: run it along a cable and watch where the light stops to locate the fault
-
See it in any light: the super-bright LED stays visible even in direct sunlight
-
Confidence before you start: a self-test confirms everything works before every job
You flip the breaker and still can't tell if a wire is live, dead, or just miswired. This non contact voltage detector pen answers that in seconds: touch the metal cap to an outlet and a green or red light tells you which wire is which, or hold it near any wire without touching it at all and the light confirms voltage is present. It runs a self-check before you start, so you know it's working before you trust the reading.
As a wire tester, it also traces a cable end to end — run it along the wire until the light goes out to find exactly where a break sits. The magnetic bit, flathead or crosshead depending on your pick, is chrome vanadium steel that resists wear, and a smart chip inside keeps every reading steady. The textured grip stays put in your hand, and the pen-shaped body with three LR41 batteries slips easily into a pocket or toolbag.
