Bipolar 350kV & 450kV X-Ray Tubes

Gulmay offers a broad range of oil-cooled bipolar 350KV & 450KV metal ceramic X-ray tubes providing a variety of target angles, focal spots, and power capabilities. For inspection applications that require different imaging parameters, dual and single focus X-ray tubes are available, with small focal spots for high-resolution imaging. In addition, Gulmay offers X-ray tubes with Beryllium (Be) windows for low inherent filtration.

Gulmay x-ray tubes are designed for use in the most demanding of industrial applications such as non destructive testing, security, sorting, inspection and thickness gauging.
