Hioki insulation resistance testers or megohmmeters feature all-in-one designs including built-in rugged cases and test lead storage compartments. The IR4016-20 is a single-range, 500 V/100 MΩ analog insulation resistance tester with efficient functions and features to help shorten work time associated with field insulation testing.
CAT III 600 V
Features Hioki IR4016-20 Analog MΩ HiTester
Single range testing voltage of 500 V
Test insulation resistance up to 100 MΩ
Built tough to withstand a 1-meter drop onto a concrete floor
Bright LED luminous scale
Check for live circuits and battery status
Integrated hard case for quick and easy storage without disconnecting the leads
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.
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.
Continuous monitoring of battery life
You can keep track of remaining battery life since it’s shown on the LED, eliminating the need to worry about sudden loss of battery power 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.
Remote control to start and stop insulation resistance measurement from the leads
By using switch-equipped measurement leads, you can start and stop insulation resistance measurement remotely. There’s also a handy light for improved convenience when working in dim locations.
