Demonstration Meter Vertical
Product Code : EL-LM-10388
Quick answer: The Demonstration Meter Vertical is a moving-coil demonstration meter mounted upright on a wooden stand, used by teachers to show students the parts and working of moving-coil ammeters and voltmeters. It has an 80 mm scale and measures about 115 x 115 x 175 mm. Lab Exports manufactures it in Delhi for schools, colleges and universities.

How the meter is used in teaching
A moving-coil meter works on the motor effect. A light rectangular coil sits between the poles of a permanent magnet; when current flows, the magnetic field exerts a torque on the coil, which turns until that torque is balanced by the restoring force of the control springs. Because the deflection is proportional to the current, the pointer moves over an evenly divided scale.
The vertical demonstration meter presents this mechanism at a size a class can follow. Standing upright on its wooden base, it lets the teacher point out the magnet, coil, springs and pointer in turn, and then explain how the same movement becomes an ammeter with a low-value shunt or a voltmeter with a high-value series resistance.
It suits the lesson on electrical measuring instruments in secondary physics and the first practical sessions of a college course, before students start handling bench ammeters and voltmeters on their own.
Key features
- Vertical format: the scale and movement stand upright so students at the benches can see them.
- Wooden stand that keeps the meter steady on a demonstration table.
- Scale length of about 80 mm for a clear pointer reading at the front of the class.
- Compact overall size of about 115 x 115 x 175 mm, easy to carry between rooms and to store.
- Shows the parts of a moving-coil movement for lessons on how meters work.
