e3 Diagnostics

Audiologists use tympanometry measurements to test the middle ear's mobility when changes in air pressure occur. Recorded on a graph called a tympanogram, the results of tympanometry tests offer information about air pressure in the middle ear. Middle-ear tympanometry helps audiologists diagnose hearing loss and recommend a solution such as a hearing aid.

From handheld tympanometers to desktop models that offer a complete range of middle ear tests, e3 Diagnostics has the tools you need. Our tympanometry devices will allow you to diagnose patients' hearing issues so they can improve their quality of life quickly. You can feel confident with our high-quality tympanometry equipment from respected manufacturers including MAICO, Interacoustics, Amplivox, and Grason-Stadler.

Amplivox 102 C

Amplivox Otowave 102C

Available different models (Otowave 102-C, 102-1 and 102-4) the Amplivox Otowave 102 is a handheld, portable tympanometer that provides fast and accurate middle-ear measurements with the utmost reliability. Its lightweight, ergonomic design makes it fit comfortably in your hand during testing, and allows you to conduct tests on the go.

Additionally, the Otowave 102 is easy to operate as it displays information on its high-resolution screen before, during, and after each test. After review, results can be saved within internal memory with a patient identifier, printed via infra-red connection to a printer, or transferred to a PC.
