HIGH VOLTAGE INSULATION TESTER IR3455
Maximum 5kV Test Voltage – Up to 10TΩ of Insulated
Resistance Testing
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, 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.
