Polaris® SC-500 Controller Specifications

The SC-500controller is not only the most advance controller in Kimtron’s line of x-ray controllers, but is also the most advanced x-ray controller in the NDT market.

In keeping with Kimtron’s philosophy of being “incredibly easy to do business with”, Kimtron designed the SC-500 with the end-user in mind; all components used in this unit are readily available on an off-the-shelf basis – no proprietary hardware is used enabling the end-user to fully support the unit in-house, if they so choose.

Features / Benefits
