Amplivox Otowave 102-4 Hand-Held Tympanometer

The advanced technology within the Amplivox Otowave 102-4 tympanometer makes very fast, accurate middle ear measurements possible.

The Amplivox Otowave is shaped for success in accurate middle ear measurements.

Elegantly shaped to follow the contours of a hand and with a perfect weight distribution, tests can be completed with confidence and accuracy.

The Otowave is very intuitive to use with on-screen information displayed before, during and after the test. The compliance peak, compliance peak pressure, gradient, ear canal volume and an ipsi lateral reflex test will be measured within seconds. The programmable reflex test can be configured for one frequency (1KHz) for the Otowave 102-1 and four (500, 1KHz, 2KHz and 4KHz) for the Otowave 102-4.

Results are displayed for review on a large high-resolution graphics display. Results can be:

• Saved within internal memory with a patient identifier
• Printed via an infra-red connection to the optional portable printer
• Transferred to a PC with an IrDA port, NOAH3 database with the optional Amplivox impedance module.

Lightweight and weighing just 380g, the Amplivox Otowave 102-1 is designed to be a totally portable “go anywhere” instrument which is reliable, accurate and easy to use. The Otowave 102-1 requires no external power or data cables.
