Hydrometer Analysis Apparatus (Soil Dispersion Stirrer)
Mechanical dispersion stirrer for hydrometer / sedimentation particle-size analysis of fine soils per IS 2720 (Part 4).
NABL TC-14144·
ISO/IEC 17025:2017·
Lab ID NKM/EQ-114
The dispersion stirrer prepares soil suspensions for hydrometer (sedimentation) analysis — the method used to determine the particle-size distribution of the silt and clay fractions that pass the 75-micron sieve. This grain-size data classifies the soil and predicts drainage and frost behaviour, per IS 2720 (Part 4).
What this equipment tests
- Particle-size distribution of fine soils (silt/clay)
- Hydrometer / sedimentation analysis
- Combined sieve + hydrometer grading

Frequently asked questions
What is hydrometer analysis?
It determines the proportion of silt and clay in a soil by measuring how a suspension settles over time, extending sieve analysis to particles finer than 75 microns.
Which standard is used?
IS 2720 (Part 4).
