Multifunction electrical tester Uni-T UT526

The Uni-T multifunction electrical tester is a practical instrument for comprehensive installation checks: it offers insulation resistance measurement, residual current device (RCD) testing, continuity testing, and AC/DC voltage measurement up to 440 V. Thanks to automatic voltage detection, a clear 10,000-count display, and warning indicators, it helps quickly identify faults and improve safety at work.

Uni-T UT526 is a multifunction electrical tester designed for real-world diagnostics of electrical systems. It is suitable for checking electrical installations, distribution systems, and lightning protection systems, where accuracy, reliability, and quick interpretation of measured values are essential.

The tester measures insulation resistance over a wide range and helps detect damage to cables or components in time. It also includes RCD tests with phase reversal (0°/180°) to verify proper operation of residual current devices. For field work, you will appreciate the red warning LEDs, automatic AC/DC voltage identification, and low-battery indication.
