What Does a Permeameter Do?

When characterising the porous nature of a material we measure many aspects of pore size, but often we are also interested in the material’s permeability. This is, quite simply, a measurement of its ability to allow fluid to flow through it. We can determine permeability using a permeameter, of which many different varieties exist, and this is the topic I would like to dwell upon today. Continue reading What Does a Permeameter Do?

A very versatile instrument that I’ve been looking at recently is the Compression Liquid Extrusion Porosimeter from PMI. This clever piece of equipment will measure pore volume like a mercury intrusion porosimeter, although without the use of mercury or any other toxic substance, and will also measure liquid permeability like a permeameter. What’s more, it can do so while holding the sample under compressive stress. Continue reading Compression Liquid Extrusion Porosimeter

The principles, features, functions and applications of an instrument become clearer when a specific model is examined in detail. Today we will look specifically at a liquid permeameter. This one is from a range of PMI permeameters which Meritics is very happy to recommend. Continue reading PMI Liquid Permeameter
