EngineeredCertainty
Since 1978, PMI has built the instruments R&D and QA/QC labs trust for porosity and permeability characterization — across 50+ countries.
Fuel Cell Porometer
The PMI Fuel Cell Porometer provides fully automated through-pore analysis including pore-throat diameter, pore size distribution, mean flow pore diameter, and liquid & gas permeability. The porometer’s versatility allows the user to simulate operating conditions. The instrument has special features to measure the effects of compressive stress on a sample, test temperature, sample orientation, and layered structure on pore structure characteristics. The fully automated, user-friendly Fuel Cell Porometer is an asset in quality control and R&D environments.

Built for the measurement you need
30+ instruments across pore-size analysis, permeametry, porosimetry, sorptometry, and rock-core characterization. Drag to browse, or explore the full catalog.
PYC-100A
Automated Gas and Helium Pycnometer for true volume and true density of powders and bulk solids.
Helium Porosimeter
The instrument is designed to accurately measure the effective porosity of plug-sized rock samples using Boyle's Law. The sample is placed in a sample cell.
BET-201A
PMI's BET Sorptometer is a fully automated volumetric gas sorption analyzer used to accurately measure adsorption and desorption isotherms for the characterization of surface area, pore size distribution, pore volume, and pore structure of micro- and mesoporous materials, as well as adsorption kinetics.
Gas Permeameter
The PMI Gas Permeameter provides fast and accurate measurement of gas permeability in solid, hollow cylindrical, and sheet samples.
PMI Advanced Filter Analyzer
The PMI Advanced Filter Analyzer is designed for Quality Control (QC) and R&D applications across a wide range of industries including woven and nonwoven materials, filter media, polymeric membranes, electro-spun membranes, automotive filters, battery separators, electrodes, ceramics, geotextiles and paper.
Automated Multi-Sample Porosimeter and Permeameter (MSPDP)
The PMI Multi-Sample Porosimeter and Permeameter is a fully automated instrument used to measure the porosity and permeability of plug-sized core samples. The applied confining pressure can reach up to 10,000 psi.
Automated Burst Pressure Tester
The APP Automated Burst Pressure Tester (ABPT) is designed to accurately determine the burst or failure pressure of materials, components, and assemblies. The system is available in pneumatic and hydraulic configurations.
Dean Stark Setup
PMI's Dean-Stark Extractor Setup is used to determine the fluid saturation of core samples.
Advanced Membrane Distillation Machine
The PMI Advanced Membrane Machine is designed to measure the rate of water production from saline solutions under a wide range of experimental conditions, including pressure, flow rate, and temperature. The system enables the collection of purified water under flowing liquid, flowing gas, or vacuum conditions.
Educational Liquid Permeameter (ELP-100A)
The PMI Liquid Permeameter measures the steady-state permeability of plug-sized rock samples by flowing a single-phase liquid through the core sample. During testing, a core plug is placed in the core holder and the confining pressure is applied.
