Chave de fendas testadora de tensão TOPEX 125-250V AC, 140mm, fenda 3,5mm, indicador néon, cabo transparente

Electrical work demands certainty—is that wire live or not? The TOPEX Voltage Tester Screwdriver 125-250V AC gives you an immediate, clear answer. This 140mm contact tester combines a slotted screwdriver tip with a built-in neon lamp, so you can detect AC voltage and perform light screwdriving tasks with one tool. No batteries, no complicated setup: just touch the tip to a terminal and place your finger on the end cap. If voltage is present, the neon lamp glows through the transparent handle.

Who is it for

Electricians, maintenance technicians, and DIY enthusiasts who need a quick, reliable way to verify the presence of AC voltage in outlets, switches, and wiring. It is ideal for troubleshooting household circuits (125-250V AC), checking fuses, and identifying live conductors before starting work.

Main features

• Detects AC voltage from 125V to 250V via neon lamp indicator.
• Slotted (flat-head) tip, 3.5mm wide, doubles as a screwdriver for terminal screws.
• Chrome vanadium steel blade for durability and corrosion resistance.
• Fully insulated transparent handle for safe grip and clear visibility of the neon lamp.
• Compact 140mm total length with 75mm round shaft—fits easily in a pocket or tool pouch.
• CE compliant and designed for contact testing (finger on end cap required to complete circuit).

Tips

Always test the tester on a known live circuit before and after use to ensure it is working. For accurate readings, ensure the metal end cap is touched with bare skin—gloves may insulate and prevent the neon lamp from lighting. This tester is for AC voltage only; do not use on DC circuits. Keep the tip clean and dry to maintain conductivity.
