Abstract :
A fully computer controlled system has been designed and developed for measuring the density of solids by hydrostatic weighing method. The hardware of the system has been developed around 89C51 microcontroller. In this setup density of the unknown sample is determined with the help of mean density of the two solid density standards. The overall uncertainty has been obtained to be of the order of 0.7 ppm.
