Product Introduction

Hioki insulation resistance testers or megohmmeters feature all-in-one designs including built-in rugged cases and test lead storage compartments. The IR3455 is a 5-range, 250 V to 5000 V digital insulation resistance tester offering up to 10 TΩ of insulated resistance testing.  High performance features include bargraph, built-in memory, leak current and voltage testing, and DAR and PI calculation capabilities to help shorten work time associated with field insulation testing.  

Main Features

●Measure insulation of high-voltage equipment (such as transformers, cables, and motors)

●Wide testing voltage range, up to 5.00 kV from 250 V DC

Wide measurement insulation range, up to 10 TΩ

PI (Polarization Index) and DAR (Dielectric Absorption Ratio) automatically calculated / display

Data memory function to reduce handwritten notes

Bright LED luminous scale

Extended operating temperature range of -10°C to 50°C
