Compact. Ergonomic. User friendly.

Resonance® R26M Middle Ear Analyzer provides a flexible diagnostic device for Tympanometry acoustic reflex measurement. Compact dimensions, excellent ergonomics and a luminous 7” TFT display: R26M has been engineered to respond to the needs of ENT and Audiology Specialists, operating both in clinic and medical practice. Design is user-friendly and allows both device and accessories to be safely carried around in a carrying case, available on demand.
Safe. Flexible. Customizable.

R26M offers several options for managing and archiving .pdf test-report files. Thanks to this Middle Ear Analyzer, .pdf test-report files can be initially stored in a USB-stick and then either archived into external units or printed thanks to the built-in thermal printer. Reports can be easily edited and customized with additional texts and logos. MDS software allows patient data and tests results transfer to PC even in Noah®.
Fast. Versatile. Qualitative.

R26M is built upon a 30-years experience and know-how gained in the audiological industry by Resonance®. This device offers a complete range of diagnostic Tympanometry tests. The R26M in -PT configuration includes Multifrequency Tympanometry. All configurations aim to simplify daily operations and maximize efficiency.
Comfortable. Elegant. Reliable.

Design of accessories maximizes patient comfort for the best and easiest handling of the device. Optional accessories increase flexibility and performance. Resonance® R&D collaborates with Universities and ENT specialists to identify and prioritize features that are most relevant and important to them.
