Uni-T UT261B Phase Sequence Meter

Uni-T UT261B Phase Sequence Meter

Uni-T UT261B Phase Sequence Tester The Uni-T UT261B phase sequence tester is a precise tool designed to identify phase sequence and detect missing phases in electrical systems. It is ideal for electricians and technicians needing a reliable device for quick diagnostics and analysis of electrical installations. Functionality and ease of use The UT261B accurately detects phase sequence via LED indication, simplifying identification of the correct phase sequence in three-phase systems. Missing phase detection is also visualized by LEDs, allowing for quick location of problem areas. Additionally, the meter indicates motor rotation, important when starting or diagnosing machinery. Practical operating parameters The UT261B is suitable for operation with AC voltage ranging from 90 V to 600 V and frequencies from 15 Hz to 400 Hz. With an operating current below 3 mA, it is safe and efficient to use. Convenience and portability The meter is powered by a 9V (6F22) battery, providing convenient use without the need for external power. Its compact dimensions (123 x 71 x 29 mm) and weight (180 g) make it easy to carry and use. The set includes a battery and test leads, allowing for immediate use.
