A simple and safe way to detect the presence of AC voltage in cables, mains outlets, switches, circuit breakers, and more. This non-contact voltage tester produces an audible beep and flashing red light when held within 1cm of a live source of voltage. It features an inbuilt green status light and a switchable torch LED to illuminate tests in darker environments. The tester automatically powers off when unused to preserve battery life. It operates in a test range of 90-1000VAC and is easy to use with a one-button control. The package includes 2x AAA batteries.
