Demonstration Meter
Product Code : LSK-PL-10364
Demonstration Meter (SKU LSK-PL-10364) is a large moving-coil meter in a 300 × 150 × 300 mm ABS case with glass front and rear, used to show a class how AC or DC ammeters and voltmeters work. Interchangeable plastic scales let one meter stand in for several instruments. It suits teacher demonstrations in senior secondary and college physics. The meter comes from the Science Lab Supplies factory at Plot 448, HSIIDC Industrial Area, Saha, Ambala, India, which manufactures it and quotes directly to schools, colleges, tender contractors and distributors.
Specifications
The movement is a moving-coil type with a basic sensitivity of 5 mA and 100 mV full-scale deflection and an accuracy of ±2.5%. It is housed in an ABS plastic case measuring 300 × 150 × 300 mm with glass front and rear, and the scales are interchangeable plastic plates.

Applications and Experiments for the Demonstration Meter
The meter lets a teacher explain, in front of the whole class, how one sensitive moving-coil movement becomes an ammeter or a voltmeter. It supports the moving coil galvanometer topic in NCERT Class 12 physics and electrical measurement lessons in B.Sc. and diploma courses.
- Class 12 physics (CBSE/NCERT): conversion of a galvanometer into an ammeter with a shunt and into a voltmeter with a series resistance.
- Class 10 science: showing how current and potential difference are measured in a circuit.
- B.Sc. and diploma electrical measurements: meter sensitivity, full-scale deflection and range extension.
Standard Scope of Supply
The Demonstration Meter is supplied as the moving-coil meter in its ABS case with glass front and rear, together with its interchangeable plastic scales. Shunts, series resistors, leads and a power supply are not listed and can be quoted separately.
Packing, MOQ and Lead Time
You may request one meter for a lecture room or several for a department. Each quotation specifies packing, delivery time and price for the quantity, and galvanometers or meters for student benches can be added.
As a registered exporter, Science Lab Supplies holds an Importer-Exporter Code and can ship to buyers in Ghana, Ethiopia, Tanzania, Uganda, the UAE and Saudi Arabia. The business is registered under Udyam as a manufacturing enterprise (UDYAM-HR-01-0014546) and for GST (GSTIN 06ADEPJ0574F2ZU).

Frequently Asked Questions
What is the sensitivity of the Demonstration Meter?
The moving-coil movement has a basic sensitivity of 5 mA and 100 mV full-scale deflection, with an accuracy of ±2.5%.
How can one meter show both ammeters and voltmeters?
The meter comes with interchangeable plastic scales, so the same movement can be presented as an AC or DC ammeter or voltmeter as the lesson requires.
How large is the case?
The ABS plastic case measures 300 × 150 × 300 mm and has a glass front and a glass rear.
Is the Demonstration Meter factory-made by Science Lab Supplies?
Yes. Science Lab Supplies is the manufacturer and produces the meter at its factory in Saha, Ambala, India, so enquiries are answered and quoted by the factory rather than a trader.
Related Electrical Meters
After the class demonstration, students usually move on to bench meters of their own. These four meters from the same physics range cover galvanometer, voltage, current and resistance readings and can be quoted with the demonstration meter.
