The Uni-T UT261A is a compact tester for quick checks of three-phase installations – it reliably determines phase sequence, detects phase loss, and helps verify the motor rotation direction. It operates in the range 40–690 V AC and 15–400 Hz, is powered directly from the circuit under test, and thanks to the LCD display provides a clear result in moments.
The Uni-T UT261A phase sequence tester is a practical tool for electricians, maintenance staff, and service technicians who need to quickly and safely verify correct three-phase power wiring. The instrument displays results on an LCD and supports diagnostics of both phase sequence and missing phase.
A major advantage is power supplied directly from the measured circuit, so you don’t have to worry about batteries. Low operating current (< 1 mA) and compact dimensions make it a suitable tool for everyday use in the field and in the workshop.
