The handle is high strength ABS, with a textured, non-slip surface for a positive grip. The tester undergoes strict testing piece by piece at 2,000V. It gives an indication of voltage between phases 220 to 250V, 50/60Hz (up to 500Hz). The hardened, nickel-plated blade is 60mm long with a 0.5 x 3.0mm tip. A spring steel clip secures the tester in your shirt pocket. Total length 140mm.
VDE is a standard to ensure screwdrivers and other hand tools are safe to use when working with electricity. VDE takes its acronym from the German company Verband der Elektrotechnik, who are responsible for testing and certifying tools and appliances.
