E.E.G.
E824 Digital

 

  • Stand-alone electroencephalographs with many configurations based on completely digital technology and matrix dot printing on thermal paper.
  • All numeric elaboration 512 sample/second, 18 bit converted signals as amplification, filters, etc. ensure absolute precision and reliability of EEG traces.
  • The preamplifier section, optically isolated IEC 601-1, with high rejection to noise, allows high quality recording in particular environment like operating room, intensive care unit and first aid.
  • By using the EEG keyboard, it is possible to change all the recording parameters (print speed, filters, gains, montages) from menus at different levels.
  • The printer gives the recorded signal with all the recording data like date, time, filter, sensibility, time constant, speed, etc. It is possible to have the patient's data and the impedance value for each electrode printed before the trace.
  • The instrument structure allows the execution of particular diagnostic programs like cerebral death diagnosis, long time recording and standard ambulatory EEG exam. It is also possible to add some other high performance elaboration like EEG monitoring, EEG digital archive, brain mapping and spectral analysis, evocated potentials, etc.
