The Graham Field tuning fork line is marketed under the Grafco brand, offering medical-grade precision for diagnostic hearing and neurological evaluations. These instruments are crafted from high-quality aluminum alloy, ensuring they are lightweight yet highly durable for repeated clinical use. The weighted models (C128 and C256) are specifically designed to provide a stronger, more localized vibration for testing bone conduction and reflexes, while the non-weighted higher-frequency models provide the clear, sharp tones necessary for specialized auditory exams.
