Hioki insulation testers or megohmmeters feature all-in-one designs including　built-in rugged cases and test lead storage compartments. The IR4057-50 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.

Compare measured values to pre-set reference values to generate a pass or fail judgment with the Comparator function.

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*, letting you check for insulation integrity without needing to look at the instrument.

The scale is lit by a white LED, ensuring that insulation resistance values are easy to read, even when using the instrument in a dim location.

The instrument’s measurement switch can be operated with just the thumb.

Press for a single measurement or lift up for continuous measurement of insulation resistance.
