Electrom Instruments iTIGII D


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 depending on the users need for automation, reporting, and features. It comes in outputs from 4kV to 15kV. All models can be upgraded as your needs change, without purchasing new equipment.

Electrom Instruments iTIGII MINI Motor Winding Analyzer


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 solution to motor testing in general.

The “MINI” uses iTIG II technology and software, and can do all the standard tests such as winding resistance, megohm, hipot, and surge comparison tests. It comes with TRPro, the same report software used by the iTIG II.

Electrom Instruments High Voltage Power Pack

Portable Power Pack PP II

The PP II is the only truly portable 24kV and 30kV 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.

Production Line Test Automation

Electrom Instruments offers a range of systems for Production Line Test Automation (PLTA). This can simply be additional software for the iTIG II, or complex systems including resistance measurements, AC Hipot, Surge and Partial Discharge tests. Systems include automatic lead switching for automated sequences of tests.
