A fundamental safety device for any electrician or homeowner, our voltage tester quickly and reliably confirms the presence of AC voltage. Its non-contact design allows for safe detection of live wires through insulation, with audible and visual alerts. For direct testing, it features probe tips and a simple light-up indicator. This pocket-sized tool is the critical first step before any electrical work, helping to prevent accidental shock by identifying energized circuits in outlets, switches, and fixtures.
