Description

The VICTOREEN Model 7200 Double Check is a portable, easy to use, daily check device for linear accelerator quality assurance. Ten chambers are positioned to simultaneously check beam constancy, symmetry, flatness, and energy constancy. Nine chambers are used for verification of flatness, symmetry, and dose constancy while a special filtered chamber provides energy constancy information. Its unique, detachable detector and the included 50 ft (15.24 m) cable allow the Model 7200 to be used as a single module or a two-piece, remote readout device. The large LCD display, accessible internal measurement storage, and computer interface provide for ease of use, comparison, and record keeping.
