Phase Sequence and Open Phase Tester
This essential instrument is designed for checking and monitoring the presence of open phases and phase sequences in three-phase power applications. It offers fast and accurate measurement results, communicated through designated LEDs and an audible buzzer. The unit includes interchangeable crocodile clips, though any type of probe can be used. It also comes with a protective carrying case to keep your testing kit in excellent condition.
