EXTRAVOLT-350 / P2000 – is two-pole, cable X-ray unit of constant potential which is used in the radioscopy and radiography of large-size light-alloy and steel castings, welds of big thickness and similar objects.
This high-stable unit of medium power capacity was developed for the joint use with cermet X-ray tubes of the company Thales Electron Devices (France). This unit is recommended for the use together with X-ray TV-detectors in combined systems of radioscopy and for the high-quality radiography on the X-ray film or reusable phosphorous plates.
