Description

The UNI-T UT511 is a handheld insulation resistance tester built around a microprocessor system and intuitive readout design. It integrates a high-resolution LCD (9999-count) with an analog bar graph typically 30 segments to deliver clear, precise measurements in a range of testing environments.

Supporting test voltages of up to 1 kV DC (and 750 V AC), the UT511 tackles a wide range of measurement scenarios. It covers insulation resistance from low megaohm values up to around 10 GΩ, making it versatile for assessing cable or equipment integrity.

Constructed with a rugged body, this device includes essential safety certification (such as CAT III 600 V / CAT II 1000 V) to support field reliability. Powered by eight LR14 batteries, it remains compact and portable—ideal for routine diagnostics across industrial, residential, and commercial settings.
