Electricians and DIY enthusiasts rely on the kwb Single-Pole Voltage Tester to quickly check for the presence of AC voltage in sockets, switches, and wiring. Its slim, screwdriver-like design slips easily into a pocket or tool pouch, making it a convenient everyday companion for installation and maintenance work.

Key specifications

• Tester type: single-pole voltage tester
• Voltage range: 125 – 250 V AC
• Frequency range: 50 – 500 Hz
• Display: neon indicator lamp
• Tip: slotted screwdriver blade, hardened steel
• Handle: transparent plastic, fully insulated shaft
• Length: 190 mm
• Power source: passive, no battery required

Why choose it

The tester operates on the capacitive principle, using your body as a reference to detect phase voltage. The neon lamp glows when voltage is present, giving a clear, immediate indication. Its fully insulated shaft and VDE/GS certification provide confidence during use. No batteries means it is always ready when you are.

Ideal use cases

• Checking for live wires before working on electrical installations
• Identifying phase conductors in sockets and switches
• Quick troubleshooting of lighting circuits
• Verifying voltage presence in extension cords and power strips

Good to know

This tester is intended for AC voltage only and is not suitable for DC circuits. For a complete safety check, always use a two-pole voltage tester to confirm absence of voltage before touching conductors.
