Uni-T UT512 is a modern high-voltage insulation resistance tester for diagnostics of electrical installations and industrial equipment. It offers test voltage up to 2500 V, measurement up to 100 GΩ, PI and DAR functions for evaluating insulation condition over time, and a clear display with a 30-segment bar graph. Thanks to memory for 18 sets, USB communication, and PC software, you can easily save and evaluate results, while safety is enhanced by automatic discharge and high-voltage indication.
The Uni-T UT512 high-voltage insulation tester is designed for professional measurements on equipment such as transformers, generators, and high-voltage motors. With selectable test voltages of 500 V, 1000 V, and 2500 V, it allows you to precisely tailor the test to a specific application and obtain reliable results in insulation diagnostics.
For advanced evaluation, the UT512 provides PI (Polarization Index) and DAR (Dielectric Absorption Ratio) functions, which help assess insulation quality over time. A large backlit LCD with an analog bar graph (30 segments) makes quick reading easier even in the field.
Practical functions and safety features support day-to-day work:
- Continuous measurement mode for long-term tests
- Auto power-off to save energy
- High-voltage indication and automatic current discharge for increased safety
- Storage of up to 18 measurement sets and transfer to a PC via USB for documentation and analysis
