SID-220W High Precision Electronic Densimeter

The SID-220W High Precision Electronic Densimeter

Accurate Density Measurement for Liquids and Light Solids

The SID-220W from Alfa Mirage Japan offers ultra-precise density measurements with a resolution of 0.0001 g/cm³. It is ideal for liquids and easily floating solids such as urethane, rubber, sponge, and wood. This instrument ensures reliable results for laboratory, quality control, and production environments.

The High Precision Electronic Densimeter is a laboratory instrument used by quality control laboratories, research institutions, and industrial manufacturers to measure the density or specific gravity of liquids and solid materials with high accuracy. Density measurement is widely used to evaluate material composition, mixture ratios, and product consistency, since density is defined as the mass of a substance divided by its volume. Accurate density data are important for verifying formulation quality, material identification, and process control in industries such as plastics, rubber, chemicals, and food production.

Electronic densimeters typically combine a high-precision electronic balance with a measurement frame that uses the Archimedes buoyancy principle to calculate density automatically. In practical use, the instrument measures the sample’s weight in air and in a liquid medium to determine its specific gravity and volume, providing fast and repeatable results. High-precision models can achieve resolutions as fine as 0.0001 g/cm³ and may also measure floating or porous solids such as rubber, wood, and sponge materials, helping professionals perform reliable density testing for material comparison, quality verification, and research analysis. 

Advanced Measurement Capabilities

In solid mode, the SID-220W calculates the volume variation factor, flags potential measurement errors, and compensates for water temperature when determining specific gravity. For liquids, only 50cc of sample is required, providing weight in air, weight in water, specific gravity, and volume measurements.
