UNI-T UT261B Motor Phase and Rotation Direction Tester

Uni-T UT261B Phase Sequence and Motor Rotation Tester
The Uni-T UT261B is a compact tester designed to check phase sequence, detect phase loss, and verify motor rotation direction. The device operates within an AC voltage range of 90–600 V at a frequency of 15–400 Hz, making it ideal for diagnosing three-phase installations and drive systems. LED indicators clearly display phase sequence, phase loss, and motor rotation direction, allowing you to quickly verify the correctness of the installation and detect any errors before starting the equipment.


Compact, ready-to-use design
With compact dimensions of 123 × 71 × 29 mm and a weight of 180 g, the UT261B is convenient for transport and daily use. The device is powered by a 9V 6F22 battery, and the included three test leads with alligator clips allow for quick connection to the installation. The kit also includes a carrying case and a user manual, making it easy to store and safely transport the tester.
