The CIRCOGRAPH DI ensures the same test quality as the CIRCOGRAPH CI with the basic functions, but this system does not have an integrated control computer. Optionally, the CIRCOGRAPH DI can be upgraded with additional functions, such as an archiving.

Operation, administration and archiving are carried out via an externally connected control computer. The system ensures a precise inspection of semifinished products for longitudinally oriented defects on the material surface. The different sensor systems ensure an optimal adaptation to the test task. Due to the compact design of the CIRCOGRAPH DI it is possible to integrate in almost any production line.
