A&D ALEW300SG Electronic Densimeter for Density and Specific Gravity Measurement in Liquids and Solids (300 g Capacity)

Electronic Densimeter for Floating Samples Measurement

Accurate and Fast Density Testing for Industrial Samples

This electronic densimeter is designed for precise measurement of specific gravity in floating materials such as urethane rubber, plastics, sponge, and wood. With a density resolution of 0.01 g/cm³ and weight capacity from 0.01 to 300 g, it delivers fast and reliable results.

The Electronic Densimeter ALEW300SG is a laboratory instrument designed to measure the specific gravity and density of floating solid materials such as urethane rubber, plastics, sponge, and wood. Density testing is widely used in materials engineering and quality control because it helps verify product composition, detect formulation changes, and confirm the consistency of manufactured materials during production and inspection processes. 

This general-purpose electronic densimeter provides a density resolution of 0.01 g/cm³ and can measure samples weighing from 0.01 g to 300 g. Using a hydrostatic measurement method similar to the pycnometer principle, the instrument determines density by weighing the sample in air and then while submerged in a liquid medium. Measurements typically take about 10 seconds, making the device suitable for routine testing on production lines where multiple samples must be analyzed quickly.

Additional features such as comparator mode for pass/fail judgments, RS232C interface connectivity for data transfer, and the ability to use ethanol or water as the liquid medium help expand its application in laboratory and industrial environments. The instrument also displays weight in air, specific gravity, and volume values, providing comprehensive material characterization for plastics, rubber, and lightweight engineered materials. 

Quick and Simple Measurement

Density and volume measurements take only 10 seconds by placing the sample in water, making it ideal for routine production line testing and quality control.

Reliable for Various Industries

Widely used in plastics, rubber, and wood manufacturing, this densimeter is praised for its ease of use, speed, and accuracy. It helps maintain consistent product quality and offers advantages over traditional hydrometers by providing digital precision and easy data recording.
