MXR-451HP/11(COMET) - COMET Xray

MXR-451HP/11

Product Description

The MXR-451HP/11 is a bipolar oil-cooled
X-Ray tube assembly with integrated radiati-
on protection. It comprises dual focal spot, a
high power tungsten anode and a directional
beam.The tube is specifically designed for
non-destructive imaging applications.
