Volt Stick SOUND The original and still the best, is an instant tester for safely checking the presence of an AC voltage, without making any disconnections in cables, wall sockets, fuses, circuit breakers, junction boxes, etc. No current flow is needed for correct operation. The red indicator in the tip will illuminate on detection of AC voltage simply by applying the tip close to any connection point, or moving it along any insulated cable. The brand new SOUND now features a detection buzzer for even greater clarification. Also ideal for `detection round corners', in bright daylight and in awkward out of sight areas. High visibility green tube for ease of identification if dropped or hidden in the toolbox. Features: * Added `Bleeper' feature * Locates breaks in cables * Detects blown fuses inside plugs or fuse holders * Distinguishes between live and neutral wires in both single and three-phase supplies * Identifies voltage-carrying cables in junction boxes * Identifies faulty in-line switches * Locates defective in-series light bulbs models are fully approved to IEC 61010-1, CAT111 1000V AC and CE.
