Import Audiometer(Ad104) — Buy in Bulk from Supplier in China

The AD-104 audiometer is a precision screening device designed for hearing tests in clinical, educational and industrial settings. It supports air conduction, bone conduction and free sound field testing across 11 standard frequencies from 125 Hz to 8000 Hz for air conduction and 250 Hz to 6000 Hz for bone conduction, with frequency error below 1%. The unit produces low-noise signals via 24-bit digital processing and offers three output options: TDH39 or plug-in air conduction earphones, bone conduction earphones, or free sound field connections to external speakers or insert earphones.

Constructed for versatility, the AD-104 accommodates pure tone, pulse and warble tone tests, as well as language and noise-language testing with simultaneous masking. It features two independent channels, 5 dB step attenuation with 1 dB accuracy, and a display that clearly shows test ear, frequency and output level in dB HL. The device also supports calibration for multiple earphone types and can operate as both a mobile and desktop unit, with keyboard-based installation and operation for ease of use.

Common applications include hearing-aid fitting, school and occupational health screenings, military and rehabilitation centre assessments. The audiometer is suited for environments requiring portable, reliable testing equipment with clear visual feedback. Buyers should confirm compatibility with their preferred earphones and calibration standards before purchase.
