Extech 480400

Phase Sequence Tester

The 480400 Phase Sequence Tester has a 40 to 600-Volt rated range for testing phase orientation of 3-phase power sources over a 15 to 400Hz frequency range. Multiline graphical LCD indicates phase orientation (clockwise or counter-clockwise) and whether each of the phases is live. No battery required. Comes complete with cable, three large color coded alligator clips, and pouch case.

Extech PRT200

Non-Contact Phase Sequence Tester

The Extech PRT200 is a non-contact phase sequence tester with a 75 to 1000 VAC input voltage and 45 to 65 Hz frequency range. This tester features LEDs that indicate whether each phase is live and that phase's orientation; a beeper sounds intermittently when correct phase is detected and continuously if phase is reversed. An adjustable Hi/Lo LED brightness switch makes it easy to take measurements in dimly lit areas or sunlight, while the CAT IV 600 Volt safety rating plus fully-insulated, wide-jaw alligator clips mean it's appropriate for industrial applications. The PRT200 comes complete with a year warranty, three built-in 30 in. test leads with large color-coded alligator clips, 4 AA batteries, and a pouch case.
