Interacoustics Impedance Audiometer AT235h This was surplussed along with about a dozen other similar machines from a local school district, and was replaced with new equipment. I don't have a power cord, and I am not qualified to determine its functionality status so I am selling it used as-is "for parts". I won't be able to take any returns on this item. Includes all of the components shown too! Please see scans. **FedEx Fast and Secure Shipping in a Box! I have limited information, but feel free to can contact me if you have any questions!
