HIGH VOLTAGE INSULATION TESTER IR3455
Model No :
HIOKI-IR3455
Part Code :
IR3455

Overview

The IR3455 is a 5-range, 250V to 5000V digital insulation resistance tester offering up to 10TΩ 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.

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 TO
- 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 ? to 50 ?

Major Applications
