Standard A440 Precision Steel Tuning Fork

Establish a perfect musical foundation with this Standard A440Hz Tuning Fork. This essential reference tool is precision-engineered to vibrate at exactly 440 vibrations per second, the internationally recognized pitch standard for orchestral tuning ($A_4$). Crafted from high-durability electroplated iron, it provides a clear, pure, and long-lasting tone that is unaffected by temperature changes. Whether you are tuning a violin, an erhu, or a guitar—or using it for educational sound physics demonstrations—this fork is the gold standard for acoustic accuracy.

Key Performance Features

• Universal Pitch Reference: Calibrated to A440, ensuring your instrument is perfectly in tune with pianos, digital tuners, and other ensemble members.

• Pure Sine Tone: Produces a clean, overtone-free sound that is much easier to tune to by ear than complex digital tones.

• Rugged Electroplated Finish: Features a high-quality chrome-style plating that prevents rust and corrosion, maintaining its resonance for years.

• Ergonomic Round Handle: Designed with a ball-end handle for a comfortable grip and optimal vibration transfer when placed against a resonant surface (like a tabletop or instrument body).

• Multifunctional Use: Beyond music, it is widely used in science classrooms for acoustics lessons and in wellness practices for auditory sensory testing.

Technical Specifications
