Easy-To-Use Voltage Detectors

The VoltAlert™ 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, you know 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. The Volt Alert 1LAC is for detecting line voltage from 20 to 90 VAC.

Operating principle Senses the steady state electrostatic field produced by ac voltage through insulation without requiring contact to the bare conductor. A red glow at the tip and a beeping noise (if not switched OFF) indicates the presence of voltage.
