Product description


Hioki insulation testers or megohmmeters feature all-in-one designs including built-in rugged cases and test lead storage compartments. The IR4056 is a 5-range, 50V to 1000V digital insulation resistance tester with efficient functions and features to help shorten work time associated with field insulation testing.
CAT III 600 V
Excluding IR4056-21

Key Features

  • 5-range testing voltage of 50 V/100 M? to 1000 V/4000 M?
  • Stable & medium-speed digital readings, 0.8 second response time of PASS/ FAIL decisions
  • Drop proof onto concrete from 1m (3.28 feet)
  • Bright LED, luminous LCD, test lead with bright LED lamp to illuminate near hand (Also available in the IR4056-21)
  • Continuity check via 200 mA testing
  • Built in AC/DC voltage meter, useful for testing solar power generation systems and electric vehicles
