The Proskit NT-309 detects the presence of AC voltage from 12 to 1000 V without requiring direct metal contact with the conductor. It is designed for electricians and technicians who need to confirm whether a wire or terminal is live before working on it.

The NT-309 includes a built-in white LED flashlight for working in dark spaces, a pocket clip for attachment to a trouser pocket or tool case, and an insulated outer surface to protect against accidental high-voltage shock. Power is supplied by two 1.5 V AAA batteries (not included).
