Part number: IR3455
The Hioki IR3455 High Voltage Insulation Tester is designed for insulation testing on transformers, generators, motors, and other heavy industrial equipment where high test voltages and extended resistance measurement ranges are required.
The IR3455 provides five selectable DC test voltages: 250V, 500V, 1kV, 2.5kV, and 5kV. Insulation resistance can be measured from 10 MΩ up to 10 TΩ, providing a wide measurement range for evaluating insulation condition on high-voltage equipment.
The tester also provides leakage current measurement from 1.00 nA to 1.20 mA across six ranges. Built-in DAR (Dielectric Absorption Ratio) and PI (Polarization Index) calculation functions provide additional information for assessing insulation condition over time.
A backlit digital LCD with a bar-graph display helps users read measurement results in different lighting conditions. The IR3455 supports multiple power options, including AA batteries, an optional battery pack, and an AC adapter, making it suitable for both field testing and longer test sequences.
The rugged built-in case includes storage compartments for test leads, helping keep the instrument and accessories organized during transportation and use.
If you need a different insulation tester, the Hioki range also includes the IR4056-20 5-Range Digital Insulation Tester. Contact GeneralTech Shop if you need help selecting the appropriate model for your application.
