IT-25B Impulse Spark Tester

The IT-25B is the Clinton Instrument Company's Impulse Spark Tester designed as an alternative to the wet dielectric test. It is primarily used when testing wire to specifications that have not adopted the high frequency spark test such as MIL-C-13777E, MIL-W-16878D, and some NEMA specifications.
