The Dukal Corporation Aluminum Tuning Forks are precision-engineered medical diagnostic instruments designed for clinical neurological evaluations, sensory loss testing, and auditory assessment. Manufactured from lightweight, non-magnetic aluminum alloy, these tuning forks deliver sustained, consistent acoustic frequencies with exceptional tonal accuracy. The 128c and 256c models feature integrated fixed weights to emphasize lower vibratory frequencies required for peripheral neuropathy screening and bone conduction testing, while the 512c model provides a clean, weightless tone ideal for Rinne and Weber hearing tests.
