The particle size distribution of fine-grained soils that pass through a 75-micron sieve is determined using the hydrometer technique. Elite Lab is manufacturer and supplier of Particle Size Sedimentation Method in Kolkata, Patna, Ranchi, West Bengal, Bihar and Jharkhand India. The specific gravity of the soil suspension in the centre of the hydrometer's bulb is measured by the instrument. The specific gravity of a solid is determined by the mass of solids present, which in turn is determined by the size of the particles.

In addition, the hydrometer approach produced findings that were equivalent to those obtained by Particle Size Sedimentation Method (Hydrometer Method) for particles greater than 43 and 53 microns. The accuracy of the hydrometer approach was not affected by the frequent insertion and withdrawal of the hydrometer from suspension, which was required in the thorough particle-size analysis process by Particle Size Sedimentation Method Hydrometer Method Manufacturers in Bihar, Jharkhand, West Bengal, Kolkata, Ranchi, Patna.
