UNI-T UT513B High-Voltage Insulation Resistance Tester 5 kV CAT IV 600V
- 5 SELECTABLE TEST VOLTAGES: Covers 250 V, 500 V, 1000 V, 2500 V, and 5000 V to match the test voltage to the asset, from control wiring to medium-voltage motor windings and transformers.; PI & DAR TIMED DIAGNOSTICS: Polarization Index and Dielectric Absorption Ratio tests reveal moisture and contamination in insulation that a single spot-check resistance reading can miss.; STEPPED-VOLTAGE PROFILING: Automatically steps test voltage in 10% increments across the selected range, exposing marginal insulation that a fixed-voltage endpoint reading would report as a pass.; 2 T MEASUREMENT RANGE & SAFETY: Reads insulation resistance up to 2 T with ±(5%+5) accuracy, features auto-discharge after each test, a high-voltage alarm, and is rated CAT IV 600 V.; 999-SET DATA STORAGE & USB TRANSFER: Stores up to 999 result sets on the instrument and transfers them to a PC via USB; a 14.8 V 5200 mAh rechargeable Li-ion battery supports a full day of field testing.

The UNI-T UT513B is a professional-grade insulation resistance tester built for demanding electrical maintenance work. With five selectable test voltages 250 V, 500 V, 1000 V, 2500 V, and 5000 V it covers everything from low-voltage control wiring to medium-voltage motors, transformers, switchgear, and long cable runs. Insulation resistance reads up to 2 T, keeping modern high-resistance insulation firmly on-scale. Beyond a basic spot check, the UT513B runs Polarization Index and Dielectric Absorption Ratio diagnostics to distinguish genuinely sound insulation from windings hiding moisture or contamination. Its stepped-voltage profiling applies voltage in 10% increments, exposing marginal insulation that a single fixed-voltage reading would pass.
Live leakage-current display, automatic circuit discharge after each test, and a high-voltage alarm round out the safety features on this CAT IV 600 V rated instrument. Up to 999 result sets can be stored onboard and transferred to a PC via USB for compliance records. A 14.8 V, 5200 mAh rechargeable lithium-ion battery supports a full day of field testing.
