Sonometers
Sonometers (Product Code: SCL-347/030) is a wooden sonometer set used to study how the sound of a stretched wire depends on its length, tension and thickness, in school and college physics laboratories. It combines a 60 cm wooden resonance box with three steel cords, three movable bridges, a dynamometer, 500 g masses and tuning forks of 512, 480 and 440 Hz. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

What Is a Sonometer Used For?
A sonometer verifies the laws of vibrating strings: the natural frequency of a wire falls as its vibrating length increases, rises with the tension, and falls as the wire gets thicker. Students slide the movable bridges to change the length, hang masses to set the tension and read that tension on the dynamometer, then switch between the 0.4 mm and 0.8 mm steel cords to see the effect of thickness.
In the classic resonance method, a small paper rider is placed on the wire and a struck tuning fork is pressed on the resonance box; the bridges are moved until the rider jumps off, showing the wire and fork share the same frequency. Repeating this with the 512, 480 and 440 Hz forks gives a set of readings for a length–frequency graph. This makes the set a standard sonometer for the physics lab in board-level and first-year college practicals.
What to Specify When Ordering
- The number of sonometers needed, usually one per practical group.
- Whether spare steel cords of 0.4 mm or 0.8 mm diameter should be quoted with the sets — ask us.
- Whether extra tuning forks or masses are required beyond those in the set.
- The delivery location, so packing for the wooden box can be planned.
OEM Manufacturer
ScienceLab is the brand of Jain Scientific Equipments Private Limited, the OEM (original equipment manufacturer) of this sonometer set. The wooden sonometer is built at the company's own licensed factory at Saha, Ambala, Haryana, India, and dispatched factory-direct to schools, colleges and laboratory dealers. Requests for replacement cords, bridges or matching sets for a new laboratory go straight to the maker — ask us. The company profile gives more background.

Frequently Asked Questions
What is included in the Sonometers set?
The Sonometers set includes a wooden sonometer of 110 x 10 x 8.5 cm with a 60 cm resonance box and scales, a dynamometer, two 0.4 mm and one 0.8 mm steel cords, three movable bridges, masses of 500 g + 6 x 500 g, three tuning forks with a hammer, and a scale.
Which tuning fork frequencies come with the Sonometers?
The Sonometers set comes with tuning forks of 512, 480 and 440 Hz and a hammer to strike them. Three frequencies let students take several resonance readings and plot how the resonating length changes with frequency.
Why does the sonometer have steel cords of two diameters?
The Sonometers set has two 0.4 mm steel cords and one 0.8 mm steel cord so students can compare wires of different thickness under the same length and tension, showing that a thicker wire vibrates at a lower frequency.
How is the wire tension set and measured?
On the Sonometers set, tension is applied by hanging the supplied masses (500 g + 6 x 500 g) from the wire, and the dynamometer is used to read the tension force, so students can vary it step by step during the experiment.
Who manufactures the Sonometers?
The Sonometers set is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), the OEM, at its own factory at Saha, Ambala, Haryana, India. Institutions, dealers and importers buy it directly from the manufacturer.
Can the Sonometers be supplied for several laboratories at once?
Yes. ScienceLab quotes the Sonometers set for single schools, multi-lab projects and dealers in India and international markets. Send the quantity, any spare cords or forks needed and the delivery location through the contact page.
