The QA700/QA700+ is a clinical audiometer offering all necessary air and bone conduction test capabilities with masking. It offers a range of test features such as Pure-tone, Speech, or QA700 Plus for additional Hughson Westlake auto test, SISI, Stenger and ABLB.
Operation is simple and intuitive. The buttons indicator lights and screen clearly show the device’s current setting contain sound level, frequency, transducer, signal type, audiogram, channel and so on. The ergonomic design is exceptional with a high resolution 7-inch color display that presents crystal clear images for easy to read audiograms. The device has various user-defined settings which enable you to acclimate quickly without losing efficiency or speed.
QA700/QA700 plus support standalone mode to monitor of test results, data storage and printing or connects to PCs running Management Software for more functions such as data sync, data export, diagnosis and printing template modification.
The QA700/QA700 plus clinical audiometer is designed to be a device for diagnosing hearing loss.
