What Is the Particle Size Analysis Set, Hydrometer Method Used For?
Particles finer than the smallest sieves cannot be graded by sieving, so their sizes are found from the rate at which they settle in water: larger particles fall faster, and the density of the suspension at a given depth falls with time. The soil is soaked in sodium hexametaphosphate solution, dispersed with the high speed stirrer and made up to 1000 ml in a sedimentation cylinder, which stands in the glass tank kept at a steady temperature by the heater. The operator reads the hydrometer and thermometer at set times, and the readings are converted into particle diameters and percentages finer. The standards listed are ASTM D 422, AASHTO T 88 and BS 1377-2.

Frequently Asked Questions
What is included in the hydrometer set?
Six 1000 ml sedimentation cylinders with rubber bungs, a 151H soil hydrometer, a glass tank, a glass thermometer, a 250 ml borosilicate beaker, a heater with thermostat and circulation unit, sodium hexametaphosphate and a high speed stirrer.
What range does the soil hydrometer cover?
The 151H soil hydrometer reads from 0.995 to 1.038 g/ml with divisions of 0.001, measuring the density of the soil suspension as the particles settle.
Why is a constant temperature bath needed?
The settling rate of particles and the hydrometer reading both change with water temperature, so the cylinders stand in the 600 × 300 × 380 mm glass tank, held steady by the thermostatic heater and circulation unit.
What is the sodium hexametaphosphate for?
It is a dispersing agent that keeps clay particles separated so that they settle individually; 1000 g is supplied, and the 4000 R.P.M. stirrer with baffle cup disperses the soil in water.
What power does the heater need?
The heater with thermostat and circulation unit is rated at 1000 W and runs on 230 V, single phase, 50 Hz.
Which standards are named for the hydrometer analysis?
For particle size analysis of fine soils with this set, the standards listed are ASTM D 422, AASHTO T 88 and BS 1377-2.
