MAICO ERO•SCAN OAE Handheld Diagnostic & Screening Device | TEOAE & DPOAE Auditory Testing

The MAICO ERO•SCAN OAE is a versatile otoacoustic emissions testing device designed for both screening and diagnostic audiology needs. It enables objective assessment of cochlear (outer hair cell) function using TEOAE and DPOAE protocols. Its dual mode functionality allows clinics or mobile units to conduct quick Pass/Refer screening or more detailed diagnostic evaluations.

With its high noise-immunity algorithm, ERO•SCAN delivers reliable performance even in standard clinical settings with background noise up to approx. 55-65 dB SPL, reducing false refer rates. The unit is highly portable: compact design, handheld ear probe, rechargeable battery capable of delivering around 1000 tests (minimum ~15 hours continuous use).

The OLED display provides clear graphical feedback (line and bar diagrams) and shows results in an easy to interpret Pass/Refer format for screening, while diagnostic mode offers richer data and customizable test protocols. The device stores ~250 tests internally; results can be transferred to PC via compatible database software (MAICO Sessions, HiTrack, OZ, etc.), and optionally printed using wireless printer.
