They are ideally suited for diverting large electrical surges caused by lighting, EMP and other sources of high voltage, high current transients.
Teledyne Reynolds' standard spark gaps are constructed using only the highest quality, high alumina ceramics that have been metallized and plated. The brazing and gas filling process is computer controlled, resulting in a brazed joint between the electrodes and the ceramic body that is rugged and reliable.
Except for 90 volt versions, all standard TRI spark gaps contain minute amounts (maximum of 10 μCi) of Tritium backfill gas. Each gas tube is identified with the international radiation symbol, H.
