Advanced Permeability Porosimeter

The PMI Advanced Permeability Porosimeter is a versatile and accurate instrument used to determine properties such as particle size, particle distribution, pore tortuosity, pore number fraction, pore throat ratio, pore fractional dimensions, permeability, material compressibility, total pore volume, surface area, and bulk and absolute densities of solid and powder samples. With unlimited user-defined data-points, automated data collection and reduction, non-destructive testing, and the least mercury exposure of any porosimeter on the market, PMI’s Permeability Porosimeter is safe, reliable, and precise. It also allows testing under ambient or elevated temperatures to simulate actual operating conditions.

Automated Pulse Decay Porosimeter/Permeameter

The rock core sample is loaded in a holder and confining pressure is applied. The system is then charged with test gas to the desired pore pressure. Adequate time is given to allow this pressure to fully saturate the sample. After reaching equilibrium the upstream and downstream portions of the system are isolated from each other. A pulse is then created by raising the upstream pressure (or lowering the downstream pressure). Data is recorded throughout this process and is used in conjunction with known system volumes to calculate gas flow rates and permeability.

Confining Pressure: Up to 5000 psi with a suitable pressure transducer be provided for measuring the pressure up to 5000 psi.Core Holder: Hassler type of core samples of 1.0 inch and 1.5 inch diameter for grain volume/ pore volume measurement.
