Bulk Densimeter / Bulk Density Meter – Particle density and Porosity of Porous / Absorbent Material, hydrophilic, Foam and Sponge


Bulk densimeter is a property of powders, granules, and other “divided” solids, especially used in reference to mineral components (soil, gravel), chemical substances, (pharmaceutical) ingredients, foodstuff, or any other masses of corpuscular or particulate matter. It is defined as the mass of many particles of the material divided by the total volume they occupy.

The total volume includes particle volume, inter-particle void volume, and internal pore volume.

Applicable for , Fine ceramic ,Brick, Powder metallurgy parts, Oil-bearing, Sponge / Foam, Rock / Stone, Absorbent materials
