The GSI 61 is a fully featured two channel clinical audiometer providing air, bone, masking and speech facilities through a range of transducers and stimulus variations with intensity steps of 1, 2 or 5dBHL. A large clear display shows investigation progress in numerical or graphical format. Other on-screen facilities include stop watch, speech scorer and patient response and settings of all controls and selections. The standard frequency range is 125Hz - 8KHz with a high frequency option up to 20KHz. A variety of free field systems will provide 90, 96 or 102dBHL sound field output. External inputs are available for CDs and tapes and an optional printer output. NOAH compatible. Separate calibrated output sockets for insert phones.
The GSI 18 is a single channel, manual audiometer. It is a direct replacement for our GSI 17. Its stylish design along with its portability, built-in battery compartment and ability to store calibration data for both TDH 39 and EAR 3A or 5A insert phones makes the GSI 18 the ideal solution for school system and industrial hearing screening programs.
