## Description

The Wiha Non-Contact Voltage Detector is a professional-grade testing instrument designed for safely detecting live electrical cabling and wires from 12V to 1,000V AC. This contactless voltage tester provides an essential safety check for electricians and contractors working with electrical installations, offering both optical and audible signals to indicate the presence of voltage without direct contact. Once switched on, a permanently green LED confirms the tester is ready for use. During voltage testing, the multi-colour LED system provides clear visual feedback, illuminating blue for weak electrical fields, orange for moderate, or red for strong signals, allowing you to assess field strength at a glance. The audible alarm provides additional confirmation in noisy environments or when visual access is restricted. The device is ideal for locating breaks and cable interruptions, identifying blown fuses, testing defective light bulbs on light chains, and verifying whether circuits have been safely isolated before work commences. Its compact, pocket-sized design features a push-on clip for convenient carrying in shirt or trouser pockets, whilst the IP67 protection class ensures reliable operation in demanding site conditions. An integrated flashlight allows you to illuminate measurement points in dark environments such as loft spaces, consumer units, or under-floor areas, and can be operated independently as a standalone torch. The tester automatically switches off after four minutes of inactivity to conserve battery life, with 2 x AAA batteries supplied. Designed for CAT IV 1,000 VAC applications, this single-pole voltage tester complies with EN 61010-1/IEC 61326 standards. The internationally compatible measurement tip suits all socket variants worldwide, making it suitable for both domestic and international electrical work. Always test the voltage tester on a known voltage source before and after every use to ensure correct operation.
