Product details:

The Extech by FLIR noncontact tester checks phase sequence and status on 3-phase power sources. Essential LEDs indicate orientation (CW or CCW) and whether each phase is live. Beeper indicates the phase detected and if it is reversed. Durable housing has a magnet to attach to an AC distribution panel for ease-of use. 3 built-in, 30" test leads have color-coded, fully insulated alligator clips.
