KWB Comprobador de tensión unipolar 120-250 V AC, indicador de neón, punta plana de 3 mm, transparente/rojo 143000

This KWB single-pole voltage tester stands out with its transparent housing and integrated pocket clip, making it a practical companion for quick phase detection in AC circuits. Unlike bulkier two-pole testers, it offers a slim, screwdriver-like form factor for one-handed checks.

Highlights

• Detects AC voltage from 120 to 250 V via capacitive coupling
• Neon lamp indicator glows when voltage is present
• Fully insulated shaft with 3 mm slotted tip doubles as a screwdriver
• Self-powered – no batteries required
• Transparent housing with red accents and pocket clip

In daily use

Grip the insulated handle, touch the tip to a live conductor, and place a finger on the metal cap at the end. The neon lamp lights up when AC voltage is detected. The pocket clip keeps the tester within reach on a shirt or tool pouch.
