STONEC 3.0mm x 140mm Electric Mains Voltage Tester Screwdriver (AC 100V–500V) - Insulated Clear Handle with Neon Indicator Bulb & Pocket Clip
STONEC 3.0mm x 140mm Electric Mains Voltage Tester Screwdriver (AC 100V–500V) - Insulated Clear Handle with Neon Indicator Bulb & Pocket Clip
-
The STONEC® Voltage Tester Screwdriver (3.0 x 140 mm) is an essential diagnostic safety tool for electricians, maintenance technicians, and DIY users to quickly verify live electrical AC circuits. Built with a slotted 3.0 mm tip and a fully insulated transparent handle, it houses a high-sensitivity neon lamp resistor assembly. When the screwdriver tip contacts a live conductor (AC 100V to 500V) and the operator touches the metallic contact cap at the end of the handle, the internal neon bulb glows bright to signal the presence of live voltage. Features a integrated metal pocket clip and hanging plastic header tag for convenient storage and portability.
