|IR4017-20||500 V/ 1000 MΩ, Test Lead L9787 bundled|
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.
