Suitable for assessing the specific gravity of floating materials like urethane rubber, plastics, sponge, and wood when submerged in water

Electronic Densimeter

Fast, Simple Density Testing for Production and Quality Control

The Alfa Mirage EW-300SG Electronic Densimeter is designed for rapid and repeatable specific gravity measurements of floating materials such as urethane, rubber, plastics, sponge and wood. By combining hydrostatic density measurement with a simple operating procedure, it enables laboratories and production facilities to obtain accurate density values in approximately 10 seconds without lengthy calculations or complex preparation.

Manufactured in Japan, the EW-300SG is particularly well suited for routine quality control where large numbers of samples must be inspected quickly. Its compact footprint, intuitive operation and integrated RS-232C interface make it an excellent solution for manufacturing environments as well as laboratory testing.

Ideal for Production Line Density Verification

Unlike high-end laboratory densimeters intended for research applications, the EW-300SG focuses on speed and ease of use. Operators simply immerse the sample in the measuring liquid and the instrument automatically calculates specific gravity and volume. This allows manufacturers to rapidly verify material consistency while minimizing operator influence on the results.

Because measurements are completed in about 10 seconds, the instrument is especially valuable for production-line inspection, incoming material verification and routine quality assurance programs.

Optimized for Floating Materials

The EW-300SG has been specifically developed for lightweight materials that naturally float in water. Typical applications include urethane foam, sponge, rubber compounds, plastics and wood. It can also determine density changes during production, helping manufacturers maintain consistent material properties.

The improved Styrol water tank also allows ethanol to be used as an alternative measuring medium when required by the application.

Simple Operation for Maximum Productivity

Quick Measurements

Density and volume measurements are completed in approximately 10 seconds, allowing many samples to be tested throughout the day with minimal operator training.

Comparator Mode

An integrated comparator function allows operators to quickly determine whether a sample falls within acceptable density limits, making it ideal for production quality control.

PC Connectivity

The standard RS-232C interface enables easy connection to compatible computers for recording measurement results and integrating the instrument into laboratory documentation systems.

Reliable Quality Control

The EW-300SG conforms to recognized hydrostatic and pycnometer measurement methods and supports industry standards used throughout plastics, rubber and materials testing laboratories. Its repeatable measurement process helps improve consistency while reducing operator variability.

Applications

The Alfa Mirage EW-300SG is widely used wherever rapid density verification of lightweight materials is required. Its combination of speed, simplicity and repeatability makes it suitable for both laboratory and production environments.
