Wiha 25506 Non-Contact Voltage Tester – CAT IV 12-1000V with LED Warning

Efficient, safety-focused voltage detection in a compact hand tool

Meet the Wiha 25506 Non-Contact Voltage Tester, a compact instrument designed for fast, non-invasive checks around energized equipment. Built for Category IV environments, it detects AC voltages from 12 to 1000 V using a precise proximity sensor, helping you assess live circuits without direct contact. When voltage is detected, the transparent LED tip lights up red and an audible warning sounds, delivering immediate feedback while you keep your hands away from potentially hazardous terminals. The universal measurement tip adapts to international outlets and connectors, making it a versatile companion for professional electricians, maintenance technicians, and serious DIYers who value safety and efficiency.
