Demonstration Meter, Dial (Product Code: SLE/ME/54) is a large-scale meter dial used to show current readings to a whole class during electricity demonstrations in school and college physics labs. Its laminated plastic panel measures 315 x 115mm, and a sealed moulded box at one end holds the shunt or voltage multiplier matched to its 2.5-0-2.5mA DC scale. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Teachers use a demonstration meter dial when a small bench meter would be unreadable from the back of the room. The 2.5-0-2.5mA DC scale has its zero in the centre, so the pointer can swing either way. That makes it well suited to showing the direction of small currents, for example when a magnet is pushed into and pulled out of a coil, or when the connections to a simple cell are reversed.
As a demonstration model for the physics lab, the dial lets the whole class read the same value at the same moment. Because the shunt or multiplier is sealed inside the moulded box, the scale and its matching component stay together between lessons. Connect it in series with the circuit, include a protective resistance when trying a new arrangement, and make changes gradually so the pointer does not hit the end of the scale.
ScienceLab is the trading name of Jain Scientific Equipments Private Limited, the OEM (original equipment manufacturer) of this Demonstration Meter, Dial. The dial is produced at the company's own licensed factory at Saha, Ambala, Haryana, India, rather than bought in from a trader, and it is supplied factory-direct to schools, colleges, institutions, dealers and importers.
Because the maker handles your enquiry directly, questions about matching scales, replacement dials or repeat orders for additional classrooms go straight to the manufacturer — just ask us. More about the company is on the ScienceLab profile.

What scale does the Demonstration Meter, Dial have?
The Demonstration Meter, Dial has a 2.5-0-2.5mA DC scale with zero at the centre. The pointer can deflect in either direction, so the class can see both the size and the direction of a small direct current during a demonstration.
How large is the Demonstration Meter, Dial?
The Demonstration Meter, Dial is built on a laminated plastic panel measuring 315 x 115mm. The large panel is intended for teacher demonstrations, where students seated across a classroom need to read the scale without crowding around the bench.
What is inside the moulded box on the Demonstration Meter, Dial?
The sealed moulded box at one end of the Demonstration Meter, Dial contains the shunt or voltage multiplier appropriate to its scale. Keeping this component sealed with the dial means the correct range is always in place whenever that dial is used.
Who manufactures the Demonstration Meter, Dial?
The Demonstration Meter, Dial is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer with its own licensed factory at Saha, Ambala, Haryana, India. Quotations, repeat orders and questions about replacement dials are handled directly by the manufacturer.
Is a calibration certificate supplied with the Demonstration Meter, Dial?
A calibration certificate is not listed for the Demonstration Meter, Dial. If your institution needs one for inspection or tender records, mention it through our contact page when requesting a quote, and we will discuss what can be provided.
What should a quotation request for the Demonstration Meter, Dial include?
For the Demonstration Meter, Dial, tell us the scale you need, the number of units, whether a complete demonstration meter is required and the delivery destination. These details let the manufacturer quote accurately the first time.
Quotes for the Demonstration Meter, Dial (SLE/ME/54) come direct from the manufacturer. Send your requirement through the contact page or add the item to the enquiry cart, stating the scale and quantity you need.
