Demonstration Meter
Product Code : LSK-PL-10364
Demonstration Meter (SKU LSK-PL-10364) is a large moving-coil meter in a 300 x 150 x 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. Science Lab Supplies manufactures the meter in its Plot 448, HSIIDC Industrial Area unit at Saha, Ambala, India, and lecture-room or department quantities are quoted from there to schools, colleges, tender contractors and distributors.
Specifications
Movement, sensitivity, case and scales of the classroom demonstration meter are tabled one fact per row. In short, a moving-coil movement with 5 mA and 100 mV full-scale deflection and ±2.5% accuracy sits in a 300 x 150 x 300 mm ABS case with glass front and rear, and its interchangeable plastic scales change the role.

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, set from a Resistance Box.
- Class 10 science: showing how current and potential difference are measured in a circuit, then repeating the readings on a slide-scale Basic Meter.
- 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 for the lesson can be added as separate lines on the same quotation.
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 to the same document for one delivery.
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). Demonstration and bench meters can be requested together through the contact page or the enquiry cart, with formal bids handled on the lab tender page.
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%, which a class can follow on the large scale.
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 x 150 x 300 mm and has a glass front and a glass rear, so the moving coil can be seen working from both sides.
Is the Demonstration Meter factory-made by Science Lab Supplies?
It is. The movement is fitted into its glass-fronted ABS case at the company’s Saha, Ambala, India factory, and enquiries are answered and quoted by that factory rather than a trader.
