Solid densitometer is an instrument designed to measure the density of solid materials. It operates based on the principle of buoyancy or displacement, often using Archimedes’ principle. The sample is weighed in air and then immersed in a fluid (typically water) to determine its volume. By comparing these measurements, the density is calculated as mass per unit volume. Solid densitometers are widely used in industries such as materials science, manufacturing, and quality control to ensure the consistency and properties of materials like metals, plastics, ceramics, and composites. They offer high precision and can handle samples of various shapes and sizes. Some advanced models feature automated functions and temperature control for enhanced accuracy. Solid densitometers are essential tools for material characterization and research.
