|Hioki insulation 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, 500V/1000MΩ analog insulation
resistance tester with efficient functions and features to help
shorten work time associated with field insulation testing.
Model No. (Order Code)
CAT III 600 V
• Single range testing voltage of 500 V
|Single 500 V/1000 MΩ range with simple, easy-to-read scale for insulation resistance values|
|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.
