The Electric Relative Density Apparatus is suitable for measuring maximum density and minimum porosity ratio of the soil with the grain size less than 5mm of non-cohesive soil and the mass of the specimen with the grain size of 2 – 5mm is not more than 15% of total mass of the specimen so as to calculate the relative density of the soil. It consists of drive system, control panel, vibration hammer etc.
