GSI 18™
offers three signal modulation and two transducer options for all filtering environments. In a school screening environment, the operator can more easily test his hearing on a distracted child with a more interesting signal. In an industrial screening environment, the operator can present a signal that allows the patient to distinguish the signal from the "ringing" in the ear.
MORE SOLUTIONS FOR RESULTS
GSI 18 is the logical choice for any screening environment. The full frequency and intensity range allows for easy screening or more advanced air conduction thresholding. Patient response knob, stimulus modifications and optional dual transducers make it ideal for a variety of patient populations.
FLEXIBILITY:
Take advantage of the GSI 18's features on the go. This minimal weight portable audiometer is perfect for transporting from one location to another. Don't limit your testing to the power source. Choose between mains operation or battery operation. Five AA batteries provide 10 hours of testing.
QUICK CHARGE:
Easily switch between over-the-ear and in-ear headphones as the environment requires. GSI 18 audiometer includes calibration of two air conduction transducers. Adhere to infection control rules with disposable earplugs.
FULL FREQUENCY AND DECIBEL RANGE
Easily obtain comprehensive air conduction results over the full frequency range (125 Hz to 8000 Hz) and the ample decibel range (0 dB to 100 dB).
THE BASICS:
In 1949, Rufus Grason and Steven Stadler co-founded Grason-Stadler (GSI). In the early days, the products were used as tools for behavioral research. They were used by university psychology departments, the pharmaceutical industry for drug research, and NASA's Project Mercury for training the first space chimpanzees, Ham and Able. Since the release of its first commercially available audiometer in 1952, GSI has been manufacturing electronic medical instruments used for hearing research and clinical measurement.
