Introducing VoltAware™, the sleek, non-contact voltage tester designed by the innovative minds at IDEAL. It's easy to use and packed with features that will help you on the job. VoltAware quickly identifies hot conductors, breaks in wires and the presence of AC voltage at receptacles, switches, electrical panels, wires and cables. A green light informs you the VoltAware is on and ready, while a bright flashing red light alerts you to voltage presence. The audible indicator gives you the option to turn the sound on or off in sensitive environments. And the easy on-off twist allows you to conserve battery power when you're done for the day. The VoltAware is perfect for electricians or maintenance personnel who need to quickly test for energized circuits.
