Specific Gravity Buoyancy Balance

About Specific Gravity Buoyancy Balance

Specific Gravity Buoyancy Balance is a precision-engineered laboratory instrument used for determining the specific gravity, density, and water absorption of aggregates, concrete, and similar materials. The apparatus works on Archimedes principle, where the buoyant force acting on a submerged specimen is used to calculate its density.

The equipment comprises a rigid support frame with an integrated water tank, density basket, suspension hook, and electronic weighing balance. A mechanical lifting arrangement allows smooth immersion of the specimen in water for accurate measurement of weight in air and water.

It is widely used in civil engineering laboratories, construction material testing labs, research institutes, and quality control departments for fast and reliable testing results.

Working Principle

The apparatus operates on buoyancy principle:

• Weight of specimen measured in air
• Weight measured when submerged in water
• Difference in weight gives buoyant force
• Specific gravity calculated using standard formula
