Lever Balance Dual Scale
Product Code : EL-B-10729
Quick answer: The Lever Balance Dual Scale is a single-pan mechanical balance with two ranges, 0-250 g in 1 g steps and 0-1000 g in 5 g steps, used for everyday weighing and specific gravity experiments in school science. It has a die-cast aluminium alloy frame, a levelling screw to set zero and a detachable pan with hook. Lab Exports manufactures it in Delhi for schools, colleges and teaching laboratories.

How the lever balance is used
A lever balance reads directly: the load on the pan turns a lever, and the pointer moves across the graduated scales, so no weights or power supply are needed. The two scales give a choice between finer reading, 1 g divisions up to 250 g, and a wider range, 5 g divisions up to 1000 g. The pointer design lets the reading be taken without parallax error.
For specific gravity, a solid is weighed in air and then again while fully immersed in water. The loss in weight equals the weight of water displaced, so specific gravity = weight in air / loss of weight in water.
- Set zero with the levelling screw, then hang the solid from the hook by a thin thread.
- Read its weight in air on the appropriate scale.
- Raise a beaker of water until the solid is fully immersed without touching the sides, and read the weight again.
- Divide the weight in air by the loss of weight in water to get the specific gravity.

Frequently asked questions
What are the ranges of the dual scale lever balance?
0-250 g in 1 g divisions and 0-1000 g in 5 g divisions.
How is zero set on the lever balance?
With the levelling screw, before the load is placed on the pan.
Can the lever balance be used for specific gravity?
Yes. The detachable pan has a hook, so a solid can be weighed in air and in water and its specific gravity calculated.
