What Is the Spherometer Demonstration Model Used For?
Reading a spherometer means combining a vertical (pitch) scale reading with the division of the circular disc that lines up with it — a step many students find hard to see on a small student instrument. The enlarged disc and the black-painted vertical scale of this model let a teacher show the method at the front of the room, explain pitch and least count, and walk through the class 11 practical on the radius of curvature of a lens or mirror before students use their own spherometers. It also suits college lecture demonstrations and science exhibitions.
Frequently Asked Questions
How many divisions does the disc have?
The listing says the disc is divided into equal parts but does not give the number, and the vertical scale is listed only with a reading of 10. Ask JLab to confirm the divisions and scale range with your quote.
Is this a working spherometer or a model only?
It is a demonstration-size spherometer for teaching the reading method. Students normally carry out the measured practical with standard spherometers, listed below.
How is it different from the other Spherometer Demonstration Model?
The other listing with the same name has a dial head of about 140 mm in aluminium with a baked stove enamel finish. This one is listed with a circular aluminium disc of about 6 cm and a black-painted aluminium vertical scale.
OEM Manufacturer
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, an educational physics equipment manufacturer in India, incorporated in 2017 and working from Hargolal Road, Ambala, Haryana. The demonstration spherometer is built at its own works instead of being bought in, so schools, colleges, dealers and importers buy direct from the maker, with a visual inspection of every piece before dispatch. The company is registered under CIN U29309HR2017PTC069123 and holds MSME Udyam registration UDYAM-HR-01-0003849 (manufacturing enterprise). JLab exports worldwide and ships to buyers in every region — for example the UK in Western Europe, Egypt in North Africa, Uganda in East Africa, Taiwan in East Asia and Paraguay in South America.
