The Hioki IR4059 Insulation Tester is a Bluetooth compatible insulation tester. It has a 5-range, 50 V to 1000 V digital insulation resistance tester with bar graph and delivers efficient functions and features to help shorten the work time associated with field insulation testing. It performs EV and HEV continuity checks as well as resistance measurement of safety conductors in building electrical equipment as defined by IEC 60364.

The IR4059 is the ideal insulation tester for a technician to use when checking the insulation resistance of an electric car, thanks to its safety features, reliable performance, and user-friendly design. Secure the insulation tester to switchboard doors or the vehicle using the magnetic strap Z5020. This novel feature allows you to perform insulation tests while checking readings at eye level.

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 (included accessory), 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. It features a robust design that can withstand being dropped onto concrete from a height of 1 m. Difficult to damage, this insulation tester is ideal for use in the field. The measurement switch can be operated with just the thumb. Press for a single measurement or lift up for continuous measurement of insulation resistance.
