Phase Sequence Indicator UT262E UNI-T contactless

UT262E UNI-T is a clamp-type non-contact phase detector designed for use in three-phase AC systems. According to the manufacturer’s official information, this model can identify phase status, detect phase sequence, indicate missing phase, locate wire breakpoints, and perform basic electrical inspection without direct contact with bare conductors. This operating principle helps reduce the risk of sparking and electric shock, making the instrument suitable for electricians, maintenance personnel, and other professional users.

The device is intended for field work where safety, speed, and clear indication are essential. UT262E provides LED and buzzer indication, allowing the user to evaluate system status quickly even in demanding environments. The manufacturer states that this model can be used for phase detection, live wire examination, electrical inspection, phase identification, phase loss judgment, and wire breakpoint search/positioning.
