Hioki IR4059 insulation resistance tester
Details
The Hioki IR4059 is a 5-range, 50V to 1000V digital insulation resistance tester. The tester can measure the insulation resistance up to 4000MΩ and has a pass/fail feature that compares the measured value against a user-set reference to provide a quick indication of the result. Furthermore, there is a low-resistance mode for accurately measuring resistances under 1KΩ. The IR4059 is the upgraded version of the IR4056, providing features such as a 1-min value display, bar graph display and a faster comparator time.
The optional Z3210 Bluetooth adapter allows exporting data to an Excel file or to Hikoi's app, where measured data can be overlaid on an annotated image. The IR4059 also now comes with a protective silicone case, a test lead with remote switch, and a pair of standard test leads with pins/alligator clips.
