The Portable Diagnostic Audiometer AD104 is a Pure Tone Audiometer, ideal for hearing screening work in schools, medical centers, hospitals, rehabilitation centers, enterprises, etc.
Test function: air conduction (AC), bone conduction (BC). Free sound field (SPK)
With a built-in microphone, easy to communicate with the tester.
With a standard USB 2.0 data interface, the Audiometry data can be saved after connecting to the workstation. According to the National. The Occupational Health Standard of the People’s Republic of China can analyze and generate professional noise diagnosis reports.
Custom report Logo and name can be set through the workstation, and an A4 or B5 format report can also be generated.
