Model No. (Order Code)

IR4018-20	500 V/ 1000 MΩ, Test Lead L9787 bundled

CAT III 600 V

Key Features

• 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

	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.
