The Uni-T UT526 Multifunction Electrical Tester is a practical tool for comprehensive electrical system diagnostics, combining insulation resistance measurement (250V/500V/1000V), RCD testing, continuity testing, and AC/DC voltage measurement up to 440V. Thanks to automatic voltage recognition, a clear 10,000-count display, and warning indicators, the user can identify potential problems faster and improve workplace safety. The model is ideal for inspecting electrical installations, power distribution systems, and lightning protection systems, where accuracy, reliability, and ease of use are essential.
Precise measurements and a wide range of applications
The meter allows for insulation resistance measurement across a wide range, enabling the detection of damage to wires and system components before they lead to a failure. RCD tests with phase reversal capability (0°/180°) help verify the proper operation of residual current devices, which directly impacts the safety of system users. Circuit continuity testing with a test current exceeding 200 mA allows for accurate verification of low-resistance connections.
Intuitive operation and clear display
A display with a resolution of 10,000 counts ensures accurate and clear reading of results, which reduces field work time. Automatic AC/DC voltage identification eliminates the risk of misinterpreting measurements, and red warning LEDs enhance safety when working with live installations. Additionally, the low-battery indicator helps prevent sudden interruptions in operation.
Robust construction and portability
The compact housing and relatively low weight make the meter convenient for transport and daily use. Powering with standard AA batteries makes it easy to quickly prepare the device for operation without the need for specialized rechargeable batteries. The included accessories allow you to start taking measurements right out of the box.
