r36m-PT

Clinical Multi-frequency Middle Ear Analyzer

The all-inclusive device.

Compact. Ergonomic. User friendly.

The Resonance R36M Middle Ear Analyzer is a flexible clinical device for Tympanometry acoustic reflex measurement. Compact dimensions, an ergonomic design and a bright 7” LCD display: r36m has been expertly engineered to respond to the needs of ENT and Audiology professionals in both clinical settings and at house calls. The design is user-friendly and allows the device and accessories to be safely transported in a durable luggage-grade padded carrying case.

Simple testing. Simpler reporting.

The r36m-PT makes it easy to manage and archive test report files. PDF reports can be stored in a USB stick during testing and then either saved to external units or printed with the built-in thermal printer. Reports can be easily edited and customized with additional texts and graphics. Our MDS Suite software allows patient data and test results to be transferred to a PC in Noah® format.

Built with decades of experience.

The r36m-PT was built with 30 years of experience in the audiological industry by Resonance®. This device has a complete range of clinical Tympanometry tests and includes Multifrequency Tympanometry with the aim of simplifying daily operations and maximizing efficiency for you and your staff.
