A hydrometer or areometer is an instrument used for measuring the relative density of liquids based on the concept of buoyancy they are typically calibrated and graduated with one or more scales such as specific gravity. Laboratory 2 hydrometer analysis atterberg limits sand equivalent test introduction grain size analysis is widely used for the classification of soils and for specifications of soil for airfields, roads, earth dams, and other soil embankment construction the hydrometer. The hydrometer is inspected visually for defects in numbering, graduating, condition, or any obvious physical defects or damage, for any loose ballast material, and the presence and correct placement of a ‘scale slippage indicator.
The distribution of particle sizes larger than 75 μm (retained on the no 200 sieve) is determined by sieving, while the distribution of particle sizes smaller than 75 μm is determined by a sedimentation process, using a hydrometer to secure the necessary data (note 1 and note 2. The objective of this lab is to measure and study density and specific gravity of different liquids by using hydrometer this gives information how light or he.

To determine the particle size distribution of soil by hydrometer method theory: hydrometer method is used to determine the particle size distribution of fine-grained soils passing 75 sieve the hydrometer measures the specific gravity of the soil suspension at the centre of its bulb. The hydrometer we offer comes with a calibration report that includes a list of actual corrections to 1/10 of a division, accuracy for temperature or density correlated to nist standards and a statement of traceablility to nist standards.
