helium porosimeters

What is a Helium Porosimeter?

A helium porosimeter is a specialized instrument used to measure the effective pore volume and grain volume of porous materials, particularly those with very small pores, such as fine-grained soils, rocks, ceramics, and powders. This instrument operates on the principle of gas displacement, specifically using helium as the displacing gas.
