IT-30B Impulse Spark Tester
The IT-30B 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.
