Demonstration Models Manufacturer, Suppliers and Exporter in India
Jaincolab Manufacturers is leading Demonstration Models Manufacturer,and supplier and Exporter in India
JaincoLab Demonstration Models are teaching models of consumer electronics equipment that let an instructor explain each circuit stage to a class, rather than take precision measurements. The range lists black-and-white (JA-DM-1115) and colour (JA-DM-1116) television models, a two-in-one cassette player and recorder trainer (JA-DM-1117), a medium-wave radio circuit model (JA-DM-1118) and a cathode ray oscilloscope working-principle model (JA-DM-1119) for electronics classrooms, polytechnics and exhibition displays.
Last updated: October 2026.
What is Demonstration Models?
Demonstration Models is a range of working, cut-away or block-diagram teaching models of common consumer electronics equipment — television receivers, radio circuits, cassette players and oscilloscopes — built so an instructor can point to each stage of the circuit and explain its function to a class, rather than for precision laboratory measurement.

Frequently Asked Questions
Q: How does Demonstration Models differ from Test and Measuring Instruments?
A: Demonstration Models are working or cut-away teaching models built for an instructor to explain a circuit's stages to a class. Test and Measuring Instruments are precision measurement equipment — meters, oscillators and analysers — used to take accurate readings during an experiment.
Q: What is the difference between the two television demonstration models?
A: JA-DM-1115 is a working black-and-white television demonstration model, while JA-DM-1116 is a working colour television demonstration model.
