B05 Electric Tester Pen Screwdriver – Neon/LED Voltage Indicator, Slotted & Phillips Bit, Insulated Pocket Electrician Tool

B05 Screwdriver Voltage Tester Pen

The B05 tester pen is a compact 2-in-1 tool combining a screwdriver and voltage indicator for quick electrical checks in sockets, switches, and wiring. Its pen-style format fits easily in a pocket and provides convenient handling for maintenance work, installation checks or everyday DIY troubleshooting.

An internal indicator light helps detect live voltage, distinguish live/neutral conductors, and trace cable interruptions.
