Quality Control
Food & Beverage

MicroDens is the portable density meter for analysis of density, Brix, NaCl and concentration in food solutions, with the same precision as benchtop instruments but in a compact format. Ideal for production line controls, goods-receiving checks and laboratory validations, it ensures traceable results compliant with international standards AOAC, ISO, ICUMSA and Codex Alimentarius.

Measurement Principle

Oscillating-tube MEMS sensor, automatic temperature compensation, calculation of Brix, NaCl, density and concentration according to international food tables and standards (AOAC, ICUMSA, Codex Alimentarius).

Density & Concentration

Sugars, Salts, Extracts

MicroDens enables the determination of density, Brix, NaCl, Baumé and Fructose in low-viscosity aqueous food solutions. Ideal for fruit juices, brines, beverages, milk and dairy products, liquid preserves and diluted sugar solutions (η ≤ 5 mPa·s).

Reference Standards
AOAC 932.14 – Soluble solids in fruit and derivatives
ISO 2173 – Soluble solids in fruit and vegetable products
ICUMSA GS2/3-1 – Refractometric dry substance
Codex Alimentarius STAN 212-1999 – Sugars and concentrated solutions standard

°Brix – Juices, beverages, light syrups (Brix ≤ 35)
Density – Diluted emulsions, aqueous concentrates, milk
NaCl – Brines, preserves, covering liquids
Baumé – Medium-concentration syrups
Fructose – Diluted solutions (η ≤ 5 mPa·s)
Accuracy ±0.0001 g/cm³ | ±0.1 °Brix
Resolution 0.00001 g/cm³ | 0.01 °Brix

Instrument limit: samples with η > 5 mPa·s (oils, honey, concentrated syrups, purées) are outside the stated specification and cannot be measured with the indicated accuracy.

WORKFLOW

How to use MicroDens

A simple operating protocol, in line with food quality systems (HACCP, BRC, IFS, ISO 22000):

Raw material receiving

Check of Brix, density or salinity on arrival of juices, beverages, brines and aqueous solutions.

Formulation preparation

Adjustment of concentrations during mixing to ensure sensory and production consistency.

Process control

In-line or at-line check of density, dilution and temperature at critical stages such as concentration or pasteurization.

Finished product

Final analysis on the packaged batch to verify label specifications and uniformity.

Shelf-life and maintenance

Periodic monitoring of samples to assess stability, sedimentation or changes in consistency.

Available Parameters

All the key values for food quality control, with certified accuracy and resolution.

Milk Control

Process monitoring and rapid screening in the dairy sector

Milk quality control

DM 9/5/1991 n. 185 • CE 853/2004 • CE 273/2008 • EU 605/2010

MicroDens offers rapid and continuous monitoring of the density of milk and its derivatives, with immediate practical value for process management in the dairy and on the farm.
Density at 15 °C is a useful parameter for daily operational control, but does not replace the cryoscope for legal checks against fraud.

How MicroDens supports process control

1. Sample collection

Before measurement, the instrument should be rinsed with 3-4 rinse cycles of ~1 mL each to condition the cell. The whole process requires about 10 mL of sample, ensuring an accurate and repeatable result.

2. Automatic measurement

Density measured with automatic thermal compensation.

3. SG 15 °C

Automatic conversion to SG 15 °C according to regulations.

4. Comparison with SG ranges

Comparison with species ranges (DM 185/1991) as an internal operational reference — not for legal purposes.

5. Rapid alarm signal

If the density is abnormal, the operator blocks the tank and sends the sample for official cryoscopic analysis.
