In a nutshell
The right choise for
With the Futech 420.46A voltage tester, you quickly and reliably verify whether electrical circuits are live before starting any work. This two-pole tester measures ac and DC voltages up to 1000V and allows you to carry out continuity tests with ease. Thanks to the fixed spacing of the measuring probes, it fits directly into standard wall sockets for fast and straightforward testing. When working in poorly lit fuse boxes, electrical panels, or service shafts, the built-in led flashlight provides immediate, clear visibility. Compliant with cat III 1000V and cat IV 600V safety standards, it gives you complete peace of mind on every job.
