Diagnostic Multifrequency Tympanometer

Compact. Ergonomic. User friendly.

The Resonance R26M-PT Middle Ear Analyzer is a flexible clinical device for tympanometry acoustic reflex measurement. Compact dimensions, an ergonomic design and a bright 7” LCD display: R26M-PT has been expertly engineered to respond to the needs of ENT and Audiology professionals. 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 r26m-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 software allows patient data and test results to be transferred to a PC in Noah® format.

Built with decades of experience.

The r26m-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.

Comfortable. Elegant. Reliable.

The R26M-PT’s expertly-designed included accessories maximize patient comfort for the best and easiest use of the device. Additional optional accessories increase the device’s flexibility and performance. The Resonance research and development team works with university research departments and ENT specialists to identify and prioritize the features most important to them. Construction with high-quality components ensures the unit will be a vital part of your practice for years to come.
