HIOKI IR4052-10 Insulation Tester (100~4000MΩ)
● Hioki insulation testers or megohmmeters feature all-in-one designs including built-in rugged cases and test lead storage compartments. The IR4057 is a 5-range, 50 V to 1000 V digital insulation resistance tester with bargraph, and delivers efficient functions and features to help shorten work time associated with field insulation testing.
● The insulation testers give you pass/ fail results using a beeping sound, LCD light, and indication right on the test lead with remote control switch (option), letting you check for insulation integrity without needing to look at the instrument.
