Digital Densimeter
The Digital Densimeter HDA838-1 is designed for precise density measurement of solid and liquid materials. It is widely applicable to industries such as rubber, plastics, wires and cables, tires, glass products, hard alloys, chemical solutions, modern energy, petroleum fuels, fine chemicals, reagents, chemical laboratories, and new material research laboratories. The instrument supports quality control, formulation verification, cost management, and density research.
Applications
(1) Rubber products: vulcanized rubber, rubber sheets, gaskets, seals, and tires.
(2) Plastic materials: plastic granules, films, sheets, foamed plastics, and molded components.
(3) Chemical solutions: liquids including solvents, acids, bases, oils, and emulsions.
(4) Glass and ceramics: solid density verification of glass, ceramics, and composite materials.
(5) Metals and alloys: density measurement of metals, hard alloys, and solid components.
(6) Laboratory and research: formulation development, density studies, and quality control.

Features
(1) Solid measurement versatility: Measures metals, rubber, plastics, granules, foams, films, gaskets, tubes, wood, glass, and composite solids using Archimedes’ principle.
(2) Liquid measurement flexibility: Supports measurement of liquids from room temperature up to 100℃, including volatile, corrosive, viscous, or emulsified fluids.
(3) High efficiency: Automatic zero tracking, quick measurement (~5 seconds for solids), and dynamic memory function for liquids.
(4) Direct reading of results: Displays density, volume, and material content percentages, including dual-material mixture proportions.
(5) Adaptable to different media: Uses water or other liquids as test medium, with temperature compensation for accurate results.
(6) User-friendly operation: Simple solid and liquid measurement steps with minimal sample volume (~50 mL for liquids).
