Equal Arm Beam Balance
Product Code : JA-M-7781
The Equal Arm Beam Balance (SKU JA-M-7781) is a two-pan school balance for comparing and measuring small masses by balancing them against known weights. This equal arm beam balance for school labs has an aluminium beam pivoting on self-aligning agate bearings, takes a load of 50 g per pan and reaches a sensitivity of 10 mg, with two sliding weights for fine adjustment. JaincoLab manufactures it in India for school science laboratories.
Specifications
The Equal Arm Beam Balance has a one-piece base moulded from high-impact styrene with three-point suspension for self-levelling, an aluminium beam pivoting on self-aligning agate bearings, a load of 50 g per pan, an ultimate sensitivity of 10 mg and two sliding weights for fine adjustment.

Applications of the equal arm beam balance for school labs
In school laboratories the beam balance is used to find the mass of small objects by balancing them against standard weights, and to show students the principle of an equal arm lever, where equal masses on equal arms bring the beam to rest in the level position.
- Measuring the mass of small solids for density and specific gravity practicals
- Comparing two masses directly in introductory measurement lessons
- Explaining the principle of moments with a balanced equal arm beam
- Weighing small quantities of materials for class experiments up to 50 g per pan
