Description

With the hydrometer method, a sample is first cleaned of organic matter. It is then weighed and dried, suspended in water, and sieved. 

The solution that passes through the sieve is transferred to a measuring cylinder with water. Hydrometer readings are then taken at regular intervals. These hydrometer readings, combined with sedimentation time, are used to determine the grain sizes according to the Stoke’s Law.

The hydrometer kit contains:

A number of hydrometers

Sedimentation cylinders

Thermometer

Glass container

Heating element with thermostat and stirrer

Soil stirrer

Various accessories

The hydrometer set is used to analyse smaller fractions of soil samples. To perform a complete analysis of the grain-size of soil samples, the granular composition test set is required for the analysis of coarse fractions and a pipette apparatus for fractions smaller than 38 μm.
