ERO•SCAN® Pro

The ERO•SCAN® Pro OAE System is available in three configurations: Screener, Standard and Clinical. The 12 frequency protocol will only appear on DP Standard or Combo Diagnostic instruments (supported by both OAE and Tymp probes). The Acoustic Reflex capability is available for any configuration of instrument, but requires a Tymp probe.
