Demonstration Lever Balance
Product Code : LSK-PL-10316
Demonstration Lever Balance (SKU LSK-PL-10316) is a teacher's apparatus for showing static forces, levers and the working principle of an analytical balance. Scale pans hang from equidistant holes along a horizontal arm, and a needle and protractor show the tilt. It serves school mechanics lessons and introductory college physics. Science Lab Supplies manufactures the balance in Saha, Ambala, India, at Plot 448, HSIIDC Industrial Area, and supplies it directly to schools, colleges, tender contractors and distributors.
Specifications
A vertical stem on a base carries the horizontal balance arm, which is drilled with equidistant holes for setting the scale pans at different distances from the pivot. A zero offset rod trims the arm to balance, and a balance needle reads against a protractor to show how far the arm tips.

Applications and Experiments for the Demonstration Lever Balance
The lever balance lets a class watch the principle of moments at work: loads placed at different holes on each side either balance the arm or tip it, and the needle on the protractor shows the result. The same set-up explains how an equal-arm analytical balance compares masses.
- Middle-school science: levers and balancing loads.
- Class 11 physics: principle of moments and equilibrium of a rigid body.
- Explaining the equal-arm principle of an analytical balance.
Standard Scope of Supply
The apparatus comprises the vertical stem with base, the zero offset rod, the horizontal balance arm with its equidistant holes, scale pans with hooks, the balance needle and the protractor. Masses to load the pans are not listed in the specification and can be quoted separately if required.
Packing, MOQ and Lead Time
A quotation can be for one demonstration balance or several for different classrooms. It will set out the packing, delivery time and price for that number, and other mechanics lab equipment in India from the same range, such as lever or moment apparatus, can share the quotation.

Frequently Asked Questions
What can be demonstrated with this lever balance?
It is designed for demonstrating static forces, levers and an analytical balance. Teachers use the equidistant holes to vary the load positions and show when the arm balances.
What is the zero offset rod for?
The zero offset rod is used to bring the empty arm to balance before loads are added, so the needle starts from the zero mark on the protractor and readings are fair.
Is Science Lab Supplies the manufacturer or a trader?
Science Lab Supplies is the manufacturer. This balance is made at its own factory in Saha, Ambala, India, and prices are quoted by the factory to the buyer.
Are masses supplied with the balance?
The specification lists scale pans with hooks but no masses. If you need a mass set, ask for it on the contact page and it can be added to the quotation.
