FAQ - Alfa Mirage EW-300SG High-Precision Electronic Density Scale:

1/ What is the EW-300SG? The EW-300SG is an electronic densimeter that determines sample density and volume via the pycnometer (hydrostatic) method. By simply immersing a sample in the built-in Styrol water tank, it completes each measurement in just 10 seconds, making it ideal for interval testing on production lines.

2/ Which industries and materials does it serve? It’s widely used across automotive, aircraft, electronics, rubber, plastics, glass, paper, food, wood, and laboratory sectors. Typical samples include solids, powders, floating items, films, pellets, and even absorbent materials.

3/ Technical Specifications:

Parameter	EW-300SG Specification
Density resolution	0.01 g/cm³
Volume resolution	0.01 cm³
Scale capacity	0.01 - 300g
Repeatability (density)	+/-0.01 g/cm³
Measuring time	10 seconds
Maximum sample size (D×W×H)	100 x 70 x 25mm

All values selectable in solid density mode; Comparator mode supports rapid GO/NG judgment based on preset thresholds.

4/ Solid Density Mode: Direct density and volume readout for immersion testing.
5/ Comparator Mode: Automatic pass/fail indication against high/low density limits.
6/ Floating Object Measurement: Supports objects that float, using improved vessel geometry.
7/ Powder Density: Configurable method for granular samples (requires optional powder density kit).
8/ Density Change Rate: Continuously measures density variation during immersion.
9/ Liquid Density Mode: Measures liquid density (water, ethanol) with temperature compensation.
These modes boost throughput and quality control on automated lines.
10/ Which liquid media are compatible? Standard operation uses water, but ethanol and other low-viscosity (<100 cP) liquids can be employed with the optional liquid density kit. The system compensates for liquid temperature changes to maintain accuracy.
11/ Interface: Standard RS-232C serial port for direct PC or PLC integration.
12/ Data Logging: Transmits weight, volume, density, and Comparator results in real time.
13/ Printer Support: Optional AD-8121B compact printer for on-site reports.
14/ Optional Accessories
Printer: AD-8121B compact dot-matrix printer
RS-232C cable (2m / 5m)
USB converter (RS-232 to USB)
Liquid density kit for non-aqueous media
Airtight windshield and dust cover
Calibration weights (50g, 100g, 200g)
15/ Calibration: Use the supplied 200g weight and distilled water to auto-calibrate weight and density modes.
16/ Routine Maintenance: Every 6 - 12 months or 1000h, clean the water tank and sample container, inspect the load cell and wiring, and verify temperature compensation accuracy.
17/ Environmental Care: Keep the unit in a dust-free, stable-temperature area; avoid corrosive atmospheres.
