AC Non-Contact Electric Voltage Detector Tester Pen 90-1000V

The next generation Volt Alert AC non-contact voltage testers are easy to use — just touch the tip to a terminal strip, outlet, or supply cord. When the tip glows red and the unit beeps, you know there is voltage present. Electricians, maintenance, service, safety personnel, and homeowners can quickly test for energized circuits in the workplace or at home.
