Wiha Non-Contact Voltage Tester WHA44309 Explosion-Proof 12-1000V AC

The Wiha Voltage Detector EX is a non-contact detector designed to locate live electrical conductors and identify faults such as cable breaks, blown fuses, and defective lighting. It provides an optical and audible indication of live voltage, with a permanently green LED showing when the device is ready. During testing, LEDs light blue, orange, or red to indicate increasing voltage strength. The device switches off automatically after four minutes of inactivity to save energy and includes an integrated flashlight for illumination in dark environments. Its compact size fits easily into a shirt or trouser pocket with a push-on clip, and the measurement tip is suitable for international usage, supporting worldwide socket variants. It is designed for CAT IV 1000 VAC operation and complies with EN 61010-1 / IEC 61326, making it appropriate for use in explosive areas when testing for live conductors and potential fault sources. The tester requires testing on a known voltage source before and after each use to ensure proper function.
