John Walker Science Tuning Forks
Tuning forks calibrated for demonstrating frequency/wavelength.
No overtones to clutter your oscilliscope screen.
Science tuning forks are similar to music forks except that they are shifted downwards slightly in frequency. Middle C in the science series is set at 256Hz compared to 261.6Hz for the music scale. This is done for convenience since tuning forks are used in physics experiments to demonstrate the relationship of frequency to wavelength. As such, it is more intuitive that adjacent octaves are either 2X or 1/2 the frequency; e.g. 128:256:512:1024, etc.
Physicists and engineers involved in acoustic research, sound wave analysis & device calibration can rely on these scientific tuning forks to deliver exact pitch for the most demanding applications.
- accurate to +/- 0.05Hz (better than 0.01% for a 512Hz fork)
- based on the C256-C512 demonstrating binary progression of octave
- view sound waveforms, Lissajous figures in physics labs
- secondary frequency calibration standard for acoustic research
- tine cross section of 4.5x4mm; click on images below for lengths
Warranty is for frequency specifications only & is voided by improper use. These tuning forks are designed for physics & engineering applications and we cannot guarantee their performance for any other uses or for metaphysical expectations.
New Agers/alternative health therapists: These tuning forks are precision instruments designed for accuracy, NOT loudness, and cannot be returned without prior authorization. If you are unsure of what type of fork you need or how they are used, call or email first. We do not carry large, low accuracy aluminum forks.
