Features
Best for measuring the insulation resistance of electric vehicles.
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.
Correct voltage selection for equipment safety needs
The IR4059's high-voltage range (500V or 1000V) integrates an ingenious safety feature. Technicians are prompted to unlock when selecting the voltage—a pivotal step to prevent accidental high-voltage application to low-voltage equipment.
With our innovative solution, precision and safety converge seamlessly, guaranteeing error-free operations every time.
Comparator function provides PASS/ FAIL decisions at a glance
Compare measured values to pre-set reference values to generate a pass or fail judgment with the Comparator function.
(also pair with insulation resistance measurement and low-resistance measurement)
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.
Significantly improve testing speed using test lead with remote switch
With these four capabilities, the test lead with remote switch L9788-10 (included accessory) will speed up the measuring procedure.
Hands-free insulation testing: Effortless readings where you need them
Revolutionize Your Testing Experience: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.
Instantly create reports by a free app (GENNECT Cross)
GENNECT Cross, a free app designed specifically for use with Hioki measuring instruments, lets you check and manage measurement results and create reports.
The software provides a range of functionality that helps manage data in the field, including photographing measurement sites, placing measurement results on photographs, and saving hand written memos.
Wireless Adapter Z3210 is necessary (sold separately).
Wireless support: Wireless communication capability for even greater convenience than legacy model
Compatible with Wireless Adapter Z3210 (optional). It transfers measurements to your smartphone or tablet and allows you to quickly create reports with field photos and drawings.
Easily transfer measurement data to an Excel® file
Excel® Direct Input function allows you to input measurement values directly and automatically into an Excel® file once the instrument's auto-hold function is activated. (Wireless Adapter Z3210 is necessary)
White LED lighting that’s easy to read in dim locations in the field
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.
Robust, damage-resistant design
These instruments feature 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.
Measurement switch designed for outstanding ease of use
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.
200 mA grounding line continuity check function
The Insulation testers can perform EV and HEV continuity checks as well as resistance measurement of safety conductors in building electrical equipment as defined by IEC 60364.
