VOLTAGE DETECTION: Neon tube lights up when voltage is detected in AC/DC circuits ranging from 100-500V; the brighter the glow, the higher the voltage.
DUAL FUNCTIONALITY: Serves as both a circuit tester and a screwdriver, featuring slotted and cross-recess tips on each end of the metal rod for versatile use.
EASY TO USE: Insert the screwdriver to the bottom, hold your finger against the end of the handle, and the neon tube will light up when electricity is present.
NEON TUBE DISPLAY: Clear neon tube indicator provides a visible, easy-to-read signal, making it simple to identify live circuits quickly and safely.
USAGE NOTE: Designed for indoor use only; avoid testing near strong light sources to ensure accurate neon tube light readings during circuit testing.
