Sonometer, Simple Pattern Manufacturer,Supplier and Exporter in India

Sonometer, Simple Pattern (Product Code: SLE/PHY/297) is a two-wire sonometer used to investigate how length and tension set the pitch of a vibrating string in school and college physics laboratories. Each steel wire has its own 50 N spring balance and wrest pin on a 1140 mm wooden resonance box, so the two strings can be tensioned and compared side by side. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is the Simple Sonometer Used For?

With two identical 30 swg wires, each on its own spring balance, this sonometer is well suited to comparison work. Students set one wire as a reference, then change the tension or the bridge spacing on the second until both sound in unison, which shows directly how frequency depends on tension and length. The large bridge spans both wires to give them the same vibrating length, while the two small bridges let each wire be adjusted independently.

It also covers the standard sonometer practicals: finding the frequency of a tuning fork by resonance with a paper rider, and plotting vibrating length against the reciprocal of frequency. Simple to set up and read, it is a practical choice of sonometer for Indian school and college labs running several groups at once. Tighten wires gradually with the wrest pins while watching the balance, stay within the 50 N scale, and slacken both wires before storage.

What to Specify When Ordering

• Number of Sonometer, Simple Pattern sets needed.
• Additional 30 swg steel wires as spares for restringing.
• Tuning fork sets to go with the sonometers.
• Delivery destination, whether within India or for export.

OEM Manufacturer

ScienceLab is the brand of Jain Scientific Equipments Private Limited, and the company is the original equipment manufacturer (OEM) of this sonometer. Its wooden resonance box is made, and the balances, wrest pins, bridges and wires are fitted and assembled, at the company’s own licensed factory at Saha, Ambala, Haryana, India, so buyers deal with the maker rather than a trading intermediary.

Frequently Asked Questions

What comes with the Sonometer, Simple Pattern?
The Sonometer, Simple Pattern is supplied with two steel wires, 30 swg and 1 metre long, and three bridges: one large bridge to span both wires and two small bridges for the individual wires. Two 50 N spring balances and two wrest pins are fitted.

What are the dimensions of the Sonometer, Simple Pattern?
The Sonometer, Simple Pattern has a wooden resonance box 1140 mm long, 125 mm wide and 100 mm high. The spring balances sit at one end of the base and the wrest pins at the other.

How is wire tension measured on the Sonometer, Simple Pattern?
Each wire on the Sonometer, Simple Pattern is attached to its own 50 N spring balance with a hook, and tightened from the opposite end with a wrest pin. Students read the tension directly from the balance while adjusting the pin.

Who manufactures the Sonometer, Simple Pattern?
