Interscale Demonstration Meter
Product Code : JA-M-7741
The Interscale Demonstration Meter (SKU JA-M-7741) is a large moving coil meter that a teacher uses in front of the class to show how ammeters and voltmeters work. This demonstration meter with interchangeable scales has a basic sensitivity of 5 mA, 100 mV full-scale deflection and ±2.5% accuracy, housed in a 300 × 150 × 300 mm ABS case with glass front and rear. JaincoLab manufactures it in India for school and college physics departments.
Specifications
The Interscale Demonstration Meter is a moving coil instrument with a basic sensitivity of 5 mA and 100 mV full-scale deflection, an accuracy of ±2.5% and interchangeable plastic scale dials selected for the range being measured, in an ABS plastic case of 300 × 150 × 300 mm with glass front and rear.

Uses of the demonstration meter with interchangeable scales
The meter is used for whole-class demonstrations: because one large moving coil movement accepts different scale dials, a teacher can show the same instrument working as an ammeter or a voltmeter on AC or DC and explain how the range of a meter is changed.
- Whole-class demonstrations of current and voltage measurement in circuits
- Explaining how a moving coil movement is turned into an ammeter or a voltmeter
- Showing the effect of changing the range by fitting a different scale dial
- Comparing AC and DC measurement with the appropriate interchangeable scales
- Supporting senior secondary and undergraduate lessons on electrical measuring instruments
Scope of supply and ordering
Each unit is one Interscale Demonstration Meter housing with the moving coil movement in its ABS case, as described above. The interchangeable scale dials are listed separately as Demonstration Meter dials; the dials, accessories and quantities required are confirmed on the quotation.
Minimum order quantity, lead time and packing are confirmed on each quotation according to the quantity and the delivery destination. JaincoLab supplies single demonstration meters to schools, bulk orders for colleges and education projects, and export consignments to buyers in Africa, the Middle East and South and South-East Asia.
Frequently asked questions
What is the basic sensitivity of the Interscale Demonstration Meter?
