The RhoVol machine is a densimetric measurement system that determines the density of an ore sample, by measurement of the mass and volume of the sample, on an individual particle basis.

The machine processes batches totally autonomously and data is displayed live as it is captured, as well as in a standard spread sheet format on a per particle basis.

The Machine is material independent and density measurement range is programmable but not restricted.
