GSI 61
Overview
The GSI 61 is the two-channel clinical audiometer from the most respected name in the audiological industry: Grason-Stadler. With its state-of-the-art, two channel design, the GSI 61 allows for fast, accurate pure tone and speech testing using phones (TDH, insert and high frequency), bone vibrator and sound field speakers for output.
It features both status and audiogram screen layouts for data presentation. And it even has an articulating screen - making the GSI 61 not only easy to use, but easy to view, too!
At Grason-Stadler, we know that speed of testing and ease of use are two of the most important considerations when purchasing a clinical audiometer. That's why we developed the GSI 61. We took the very best features from our GSI 10 and GSI 16 and designed them into the GSI 61 - all to give you everything you could possibly need to conduct tests quickly and easily, both today and in the years to come.
The GSI 61 come with everything you'll need to perform a clinic audiometric test battery with maximum speed and efficiency. Features that further enhance your testing capabilities are: dual channel control with mixing/routing capabilities which allow the operator to mix signals and direct them to either or both ears, high frequency capabilities, direct calibration for insert earphones, auxiliary inputs, scorer/counter, test storage, transfer and hard copy printouts using an HP color DeskJet printer.
Features
Speed, Versatility and Quality Thanks to nearly 50 years of experience in the audiological industry, you can count on Grason-Stadler to deliver all those things and more. But don't take our word for it. See for yourself why the GSI 61 is the only clinical audiometer you'll ever want to use! |
