Description

HIOKI Digital Insulation Resistance Tester IR4057-50

An insulation tester applies a DC test voltage and measures the leakage through the insulation. It is the instrument that says whether a cable or winding is safe to energise.

Key Features

  • Test voltage must match the circuit rating — 500 V for most installation work
  • Disconnect and prove dead before testing; the instrument outputs hundreds of volts
  • A falling reading over time matters more than one absolute number

Specifications

Insulation Range 100/250/500/2/000/4/000
Test Voltage 50/125/250/500/1/000

Specifications shown are for the base model; values vary by size. Contact us if you need the figures for a specific size.
