NEW PATENTED instrument for particle size characterisation of soil

Categories: , Tag:


We are glad to submit to your attention our NEW PATENTED instrument GSA (Grain Size Analyser) which allows particle size characterisation of soil by sedimentation according to ASTM D 422 and UNI CEN ISO/TS 17892 – 4.
Paricularly the GSA measures the finer fraction of soil from 0.1 mm to 0.001 mm.

The GSA is projected for realising multiple units till 12.

The software of GSA , easy and friendly , displays in real time the trend of the test through a grafic , giving to the operator before the end of the test , a reliable forecast of a trend useful in many cases to establish in advance the characteristic of the soil under test.


  • Range of density (specific gravity ) from 0,9000 to 1,0500 with real four decimal figures.
  • Automatic compensation of variation of temperature and Stokes law.
  • Repeatability better than 2 % .
  • All the variable parameters , density of soil, acceleration of gravity, times of data acquisition etc. are programmable by the operator.

We have a unit of GSA available for testing any soil.
