Meet the demands of Electric vehicles and solar panel arrays. Step up to a 98x!

The new 981i and 983i Teraohmmeters are designed to tackle the toughest high-resistance measurement applications where other IR testers fail to excel. Look to Vitrek to deliver the IR tester you need for your production line when it’s time to test higher voltage IR values and higher voltage solar arrays like those in today’s electric vehicle systems.

What sets the Vitrek 98x Series IR testers apart from the others?

For starters, these units are based on Vitrek’s proven DSP technology giving them the ability to work into capacitive loads where most others do not. And when it comes to output voltage range, Vitrek delivers up to 6.5 KVDC for the 981i.

Need to Perform an Insulation Resistance Test on a Multi-Conductor Cable Harness?

The 981i has the ability to directly control up to four 64 channel HV scanners, right out of the box. That is up to 256 test points and using a PC with Vitrek’s Q-Test software you can expand the count up to 1020 test points.
