Neptune 5200 Series Water-Cooled Radiation Shielded X-ray Tube

The Neptune 5200 Series is a water-cooled 50kV, 100W packaged X-ray tube designed for applications where high flux density and continuous operation are important.

Utilizing our high stability and high intensity X-ray tube technology, the Neptune 5200 Series is ideal for most industrial inspection and non-destructive testing applications that require high resolution, including plastic, metal and mechanical parts inspection. Flexible and reliable, this unit is also highly suited for use in high power XRF applications.

The 5200 Series has a brass package that utilizes 0.2 liter/min of water flow, which enables the unit to provide maximum X-ray shielding and heat dissipation. The design includes high voltage, filament and water flow connectors, making it ideal for plug and play operation.

The Neptune 5200 Series is available in wide range of targets and price points to meet your needs.
