The Graham Field tuning fork series is marketed under the Grafco brand to support clinical training and professional diagnosis. These instruments are crafted from a specific aluminum alloy that ensures tonal accuracy and durability. The 1322 model includes fixed weights on the prongs to provide the low-frequency, high-intensity vibration required for neurological reflex testing. In contrast, the 1323 and 1324 student models are non-weighted, focusing on providing a clear and sustained pitch for basic auditory screenings like the Weber and Rinne tests.
