Rydel-Seiffer Tuning Fork 64Hz 128Hz Semi-Quantitative Neurological Tuning Fork

Rydel-Seiffer Semi-Quantitative Neurological Tuning Fork (C 64 Hz / C 128 Hz)

Accurately evaluate vibration perception threshold (VPT) and screen for early peripheral neuropathy with our professional-grade Rydel-Seiffer Semi-Quantitative Tuning Fork. Engineered for neurologists, podiatrists, primary care physicians, and medical students, this 2-in-1 diagnostic instrument features a calibrated 0–8 optical scale for precise, quantitative vibration assessment.

Both models feature removable weight dampers, allowing you to easily switch between C64 Hz (with dampers attached) for semi-quantitative vibration testing and C128 Hz (with dampers removed) for standard neurological exams.

Key Features & Benefits

• Dual-Frequency Versatility (C64 / C128 Hz): Serves as a 2-in-1 tool. Keep the visual scale dampers on for 64 Hz vibration perception testing, or remove them to perform standard 128 Hz auditory and neurological checks.
• Quantifiable Visual Scale (0–8): The optical triangle scale on the dampers converges as the fork vibrates, enabling exact numerical recording of sensory thresholds.
• Early Neuropathy Screening: Essential for early detection of Diabetic Peripheral Neuropathy (DPN), impaired vibration sense (pallesthesia), and sensory loss in lower extremities.
• Medical-Grade Aluminum Alloy: Crafted from lightweight, high-strength aluminum alloy, offering maximum corrosion resistance, clear tone resonance, and smooth energy transfer through the weighted base.
