Model No. (Order Code)

CAT III 600 VDROPPROOFGuarantee3yearsCE

Key Features

• Single range testing voltage of 500 V • Test insulation resistance up to 1000 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

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. Analog MΩ HiTester IR4017-20

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.
