  • I have used Diagnosys electrophysiology systems for clinical testing and research for nearly fifteen years. The systems are reliable, easy to use and protocols readily modified to answer research questions. The few times I have had problems with the equipment, Diagnosys has quickly responded and fixed the problem.

  • As a clinical neurophysiologist in a busy pediatric clinic, I wholeheartedly believe that the equipment made available to us by Diagnosys LLC allows for the testing necessary to aid in clinical diagnostics and research. I have always felt that this family run company has been by my side each and every step of the way, despite being located in another country.

  • Celeris is the Luxury Vehicle of Electrophysiology! I love Celeris for the vision science field because it grants all investigators access to a wide variety of electrophysiological tests without requiring in depth expertise of the theory of electrophysiology. It's wonderfully simple and easy to operate.
