HIOKI 3490 | Analog Insulation Resistance Tester | 250/500/1000 V, up to 4000 MΩ
Genuine Hioki 3490 insulation resistance tester from General Tech Services LLC, Saudi Arabia, with free Saudi Arabia shipping available.
Part No. 3490
Product Overview
The Hioki 3490 is a three-range analog insulation resistance tester, or megohmmeter, designed for checking insulation in cables, motors, panels, and electrical installations. It provides selectable test voltages of 250 V, 500 V, and 1000 V DC for insulation resistance testing.
The 3490 measures insulation resistance up to 100 MΩ on the 250 V and 500 V ranges, and up to 4000 MΩ on the 1000 V range. Accuracy is ±2% of scale length across the first effective range.
For low-resistance and continuity checks, the tester provides a 3 Ω range with a 200 mA test current and a 30 Ω range with a 20 mA test current. It also includes an AC voltage range from 0 to 600 V at 50/60 Hz.
A bright LED luminous scale makes the analog needle easier to read during field testing. The tester also provides live-circuit detection, battery-status checking, and automatic discharge after insulation testing.
The Hioki 3490 is drop-proof from a height of 1 m onto concrete and operates for approximately 20 hours using four AA batteries. It is rated CAT III 600 V and is designed and manufactured in Japan.

Who This Product Is Best For
The Hioki 3490 is suitable for electricians testing cables, panels, wiring, and electrical installations.
It is also suited to motor and generator maintenance teams, contractors commissioning new wiring, and technicians who prefer an analog needle display for insulation resistance testing.
Its selectable 250 V, 500 V, and 1000 V test voltages allow it to be used for different insulation-testing requirements, while the low-resistance and AC voltage functions provide additional electrical testing capability.
How to Use It
- Confirm that the Hioki 3490 and its accessories are suitable for the intended test.
- Read the Hioki instruction manual before first use.
- Verify that the circuit is prepared for insulation testing and follow applicable electrical safety procedures.
- Select the required insulation test voltage: 250 V, 500 V, or 1000 V DC.
- Connect the test leads as specified in the instrument manual and perform the measurement.
- Allow the instrument to complete its automatic discharge function after testing.
- Use the appropriate low-resistance or AC voltage function when required.
