The easiest tester to use according to our customers


The iTIG II combines multiple testing technologies into a single instrument. From low to high voltage, all your tests can be completed with the push of a button. The iTIG II is available in four models with additional feature options and DC motor test accessories.



The iTIG II MINI is a small light tester in a briefcase type enclosure, ideal for field tests of low voltage motors. Since it can be connected to the PP-II Power Pack, it can also be used to test high voltage equipment. It is an economical, more portable motor tester solution.

Portable Power Pack PP II

The PP II is the only truly portable 18kV, 24kV, 30kV & 40kV Power Pack on the market. It connects to the iTIG II and the iTIG II MINI with low voltage cables. Data generated by the PP-II is captured, displayed and stored in the iTIG II.
