Product Code : SCL-PL-12127
Eight-Piece Welch Pattern Tuning Fork Set (SKU SCL-PL-12127) gives a full octave of aluminium alloy forks, from C 256 Hz to C 512 Hz, for sound, pitch and resonance experiments. It can be paired with resonance tubes and sonometers in Class 9, Class 11 and B.Sc. practicals. For anyone sourcing a school tuning fork set in India, Science Lab Supplies manufactures this one at its HSIIDC Industrial Area works in Saha, Ambala, and quotes it directly to institutions, distributors and tender contractors.
Specifications
The table gives each detail of the eight-fork Welch set. In short, the forks are machined from acoustic-grade aluminium alloy with a satin finish, tuned to the scientific C-major scale and stamped with frequency and note on each stem, and they travel in a moulded case with foam slots and a rubber-headed mallet.

Applications and Experiments for the Welch Pattern Tuning Fork Set
With eight known frequencies, the set lets a sound experiment be repeated at several pitches and the results plotted. It serves the resonance tube and sonometer practicals of Class 11 physics, B.Sc. sound experiments, and Class 9 lessons on pitch and frequency.
- Class 11 physics: speed of sound in air with a resonance tube at more than one frequency.
- Class 11 physics: sonometer experiments on how frequency depends on length and tension, followed by standing waves on the cord of Melde’s String Vibration Apparatus.
- Class 9 science: pitch, frequency and musical notes, set beside the seven cantilever strips of the Resonance Strips Model 7 Metal strips to show natural frequency.
- Sympathetic resonance with a matching resonance box, and beats produced by loading one prong slightly.
Standard Scope of Supply
The set includes eight aluminium tuning forks from C 256 Hz to C 512 Hz, one balanced rubber-headed striking mallet, and a heavy-duty moulded storage case with foam slots cut for each fork. Resonance tubes, boxes or sonometers are separate items that can be quoted with it.
Packing, MOQ and Lead Time
You can ask for a single set or several sets of this school physics lab equipment in India for group practicals, and the quotation gives packing, delivery time and price for that quantity. A resonance tube or sonometer can be listed alongside it.
As an exporter registered under an Importer-Exporter Code, Science Lab Supplies can ship to buyers in Uganda, the UAE, Saudi Arabia, Oman, the Philippines and Nepal. A sound bench built around these forks can be priced by sending the list on the contact page, collecting the items in the enquiry cart, or entering a tender schedule via the lab tender page.
Frequently Asked Questions
Which frequencies are in the Welch pattern set?
Eight forks on the C-major scientific scale: C 256 Hz, D 288 Hz, E 320 Hz, F 341.3 Hz, G 384 Hz, A 426.7 Hz, B 480 Hz and C 512 Hz.
Why aluminium rather than steel?
Aluminium alloy is lighter, does not rust, and gives a clean fundamental tone with a long decay time, which makes resonance easy to hear in a classroom.
Is a striker included?
Yes. A balanced rubber-headed mallet comes in the case, so the prongs can be struck firmly without marking the aluminium finish or denting the prongs.
Is Science Lab Supplies the manufacturer or a trader?
The forks are machined and tuned at the company’s Plot 448 unit in Saha, Ambala, which makes Science Lab Supplies the manufacturer of the set; every quotation for it is prepared there.
