Demonstration Meter Horizontal
Product Code : EL-LM-10387
Quick answer: The Demonstration Meter Horizontal is a moving-coil meter in a transparent case with a Bakelite base, used by teachers to show how a moving-coil meter works. Students can see the mechanism through the case while readings are taken. It has an 85 mm scale and ±2.5% F.S.D. accuracy. Lab Exports manufactures it in Delhi for schools and colleges.

How it is used in teaching
Most students use meters long before they know what is inside one. The horizontal demonstration meter lets a teacher open that box: through the transparent case the class can watch the coil turn in the magnet's field as current flows, and see the springs that bring the pointer back to zero when the current stops. The link between current, magnetic force and deflection becomes something students have seen rather than a diagram in a book.
- Mount or stand the meter where the class can see both the scale and the mechanism.
- Connect it into a simple demonstration circuit, observing polarity.
- Vary the current slowly and ask students to watch the coil and pointer move together.
- Switch off and show the pointer returning to zero under the spring control.
The horizontal format suits classroom demonstration boards. Used with the vertical and interscale demonstration meters in the same range, several readings can be shown at once in larger demonstration circuits.
