Description
The Sedimentation Hydrometer test set is used to determine particle size distribution in soil from the coarse sand size down to the smallest fractions.
In this method the sample is from organic matter after which it is dried and weighed. Next it is suspended in water and sieved.
The solution that passes through the sieve is transferred to a measuring cylinder with water.
Hydrometer readings are taken after regular intervals. Sedimentation time and hydrometer readings are used to determine the grain sizes according to the stoke’s Law.
Sedimentation Hydrometer test set consisting of soil dispersion mixer, hydrometer bath, 1pcs. hydrometer 151H or 152H, sodium hexametaphosphate 1 kg, 6 pcs. 1000 ml sedimentation cylinder, heater, circulation pump, rubber stopper and 600 ml beaker.
