Hioki IR3455-01 High-Voltage Insulation HiTester - 250/500/1000/2500/5000V


The Hioki IR3455 can generate test voltages ranging from 250V up to 5 kV. Settings can be made in steps as fine as 25V. Very high insulation resistance measurements up to 5 TeraOhms are possible!

Functions such as automatic calculation and display of PI (Polarization Index) and DAR (Dielectric Absorption Ratio). as well as step voltage tests, temperature compensation, temperature measurement, and leakage current display make the IR3455 suitable for a wide range of diagnostic applications.


  • Measure insulation of high-voltage equipment (such as transformers, cables, and motors) Automatically calculate and display PI (Polarization Index) and DAR (Dialectic Absorption Ratio)
