UNI-T UT511 Insulation Resistance Tester

Description

UNI-T UT511 Insulation Resistance Tester 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. Features: Large 9999 display with 30-segment analog bar graph. PI/DAR measurements. Comparison, upper and lower limit functions. Continuous measurement mode. Auto power off. 18-group data storage. Backlight. Auto current discharge and high-voltage output alarm. Time measurement mode, auto measure within 15 minutes. Low battery and over range indications.
