- 3-range testing voltage of 250/500 V (insulation resistance testing up to 100 Mohm), and 1000 V (insulation testing up to 4000 Mohm)
- Continuity check at 3 ohm range via 200 mA testing
- Bright LED luminous scale
- Check for live circuits and battery status
Easy-to-read scale for insulation resistance values
The Hioki 3490 is a 3-range, 250/500/1000V analog insulation resistance meter with efficient functions and features to help shorten work time associated with field insulation testing.
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.
Function rotary switch designed for maximum safety
The 3490 insulation tester has voltages grouped by application with an "OFF" position between them to help keep users from inadvertently applying the wrong voltage.
Continuous monitoring of battery life
You can keep track of the remaining battery life since it is shown on the LED, eliminating the need to worry about sudden loss of battery power in the field.
Robust, damage-resistant design
The Hioki 3490 instrument 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.
