A handheld phase-sequence and motor-rotation tester that clips onto three conductors via color-coded leads to instantly show whether phase rotation is clockwise or counter-clockwise, and which phases are energized, through onboard LED indicators. Built for 40-600V AC circuits with a CAT III 600V rating, it runs on a 9V battery and includes a soft carrying case. This unit ships with a NIST-traceable calibration certificate.
