Extech PRT200 Non-Contact Phase Sequence Tester. 75to 1000VAC (45-65Hz) The Extech PRT200 Checks phase sequence and phase status. It tests from 75 to 1000VAC (45-65Hz) with LED and audible indication. LEDs indicate phase orientation (clockwise or counter-clockwise) and whether each phase is live. A beeper sounds intermittently when correct phase is detected and continuously if phase is reversed. Durable housing with back cover magnet for attachment to an AC distribution panel for easy measurement. LED brightness is adjustable. Includes fully insulated alligator clips with wide jaws.

Extech 480403 Motor Rotation & 3-Phase Tester, Digital, Orange, 2 to 400Hz Gauge Range Phase sequence and motor rotation tester has a 40 to 600 V rated range for testing phase orientation of 3-phase power sources over a 2 to 400 Hz frequency range. LEDs indicate phase orientation (clockwise or counter-clockwise) and whether each of the phases is live. In addition, it indicates rotation direction of the motor to ensure that it doesn't get damaged from incorrect wiring. Complete with: Cable Three large color coded alligator clips Pouch case 9v battery
