The VoltAlertâ„¢ AC voltage testers from Fluke are easy to use - just touch the tip to a terminal strip, outlet or cord. When the tip glows red and the unit beeps, there's voltage in the line. Electricians, maintenance, service, safety personnel and homeowners can quickly test for energized circuits and defective grounds on the factory floor, in the shop or at home to accurately identify incorrectly wired outlets.
Additional Info: Safety rating: 1000V, CAT IV. IP40.
