The nVent GARDNER BENDER VD7504GFI DualCheck is the ultimate 2-in-1 electrical safety tool for both professional electricians and DIY homeowners. By combining two of the most essential testers into one durable unit, it streamlines your workflow and ensures you never have to search for a second tool. On one end, the Non-Contact Voltage Detector senses 50-1000V AC, allowing you to quickly check for power in cables, cords, and circuit breakers. On the opposite end, the GFCI Outlet Circuit Analyzer provides an accurate analysis of your receptacles. This dual-ended design is perfect for kitchen and bathroom renovations where GFCI protection is required by code. Safety is paramount, which is why the VD7504GFI features Bright 360° viewable LED indicator lights and a high-decibel audible alarm. Whether you are working in a brightly lit room or a dark crawlspace, you will clearly see and hear the results of your test. The GFCI tester specifically checks for seven common wiring errors: Correct, Open Ground, Open Neutral, Open Hot, Hot/Ground Reverse, Hot/Neutral Reverse, and Ground Open. Built to last, the housing is constructed from hi-impact polycarbonate with a 250 lb. Crush Rating and is tested to withstand a 10-foot drop. Backed by a Limited Lifetime Warranty, this 2-in-1 DualCheck tester provides the reliability and precision needed for testing standard 120V AC outlets and ensuring your home or job site is wired correctly and safely.
