CIRCOGRAPH CP 6.412 The least-cost version for eddy-current testing with rotating probes. This single-channel test instrument has all features required for automatic testing, e.g. interfaces for the line-related sensors and actuators for speed, flaw marking and sorting. Printer and computer interfaces allow documentation in the form of a hardcopy report or export of test results and setting data to other computer systems. Together with the space-saving rotating heads Ro 20 or Ro 35L, the CIRCOGRAPH CP is the ideal solution for integration directly in drawing lines and winders.
