The UNI-T UT513A is a 5000V digital insulation resistance tester capable of measuring resistance up to 1000GΩ. PI, DAR, timed testing, data storage and USB connectivity support insulation assessment and analysis on high-voltage electrical equipment.

Key Features

  • Selectable 500V, 1000V, 2500V and 5000V DC insulation test voltages, with resistance measurement up to 1000GΩ.
  • Polarisation Index (PI) and Dielectric Absorption Ratio (DAR) functions help assess insulation condition over time.
  • Automatic discharge and high-voltage output warning improve operator awareness following insulation testing.
  • Stores up to 18 measurement records and supports USB data transfer to a computer for further analysis.
  • Large 9999-count backlit display with a 30-segment analogue bar graph, comparison function and timed testing.
