R27A Diagnostic Audiometer

The R27A offers a complete range of diagnostic tests including air and bone conduction tests, SAL and speech audiometry. Speech
material in English and Spanish is recorded on the Resonance SD-card. Additional languages can be recorded on request. The R27A aims to simplify daily operations and maximize efficiency. Unique special tests as GAP, DLF, Quick-SIN and BKB-SIN are also available.

With compact dimensions, excellent ergonomics, and a luminous 7” LCD display, the R27A is the perfect solution to respond to the
needs of ENT and Audiology Specialists, the best solution for a growing practice. Easy-to use, functional design and portable, the
device and accessories can be safely transported in a durable luggage-grade padded carrying case, available on request.

High-quality components ensure device reliability as well as long-term operation. Recognized dependability matches with
efficiency. Test-report files, generated in PDF, can be initially stored on a USB-stick, then archived into external units or printed,
thanks to the built-in thermal printer. Reports can be easily edited and customized with additional text and logos.
