Densimeter for plastics and composites

Alfa Mirage Densimeter for plastics and composites — Density checks on plastics and composite materials

This densimeter is most relevant to plastics processors, composites manufacturers, and laboratory users who need density data for material verification and quality control. Typical use cases include incoming material checks, product development, and comparison of finished parts against target specifications.

Accurate Density Measurement for Solids and Liquids

This densimeter provides highly precise measurements of plastics, composites, and other materials, with a density resolution of 0.001 g/cm³ and a weight range of 0.01–300 g. It can also measure the specific gravity of liquids (with optional liquid kit) and record water temperature.

A precision laboratory instrument used by materials engineers, plastics manufacturers, and quality control laboratories to measure the density or specific gravity of polymer and composite materials. Density measurement is widely used in plastics testing because it helps verify material composition, detect formulation changes, and confirm the consistency of raw materials or finished products. These instruments are commonly used in industries working with polymers, rubber, composites, electronics components, and engineered materials.

Electronic densimeters for plastics typically operate using the Archimedes buoyancy principle, where the sample is weighed in air and then in a liquid medium (often water) to automatically calculate density and volume. Models such as this type of densimeter can measure samples ranging from small fragments to larger plastic parts, with density resolutions around 0.001 g/cm³ and measurement ranges up to approximately 300 g. The instrument can measure both solid materials and, with optional accessories, liquids, providing fast density readings—often in about 10 seconds—for efficient laboratory testing and materials development workflows.
