Pore Size Analyzer

Advanced Pore Pro Porometer

The PMI Pore Pro Porometer is a low pressure instrument designed for the determination of pore size in geotextile fabrics. The robust instrument is easy to use and provides fast and accurate testing results on a variety of geotextile samples. Conforms to standard ASTM 316-03.

Pore Size Range: .3-500 micronsPressure Range: 20 psi

Pore Size Analyzer

Automated Filter Cartridge Tester

The PMI Automated Filter Cartridge Tester provides fully automated through-pore analysis of complete filter cartridges across a wide range of geometries.

Flow Capability: Up to 200 LPM (standard) / Up to 10,000 LPM (optional)Pore Diameter: 0.013 – 200 µm (0.002 µm with Capillary Condensation Flow Porometer)

Pore Size Analyzer

Automated Humid Air Porometer

Advanced Automated Porometers yield very objective, accurate and reproducible results, considerably reduce test duration, and require minimal operator involvement. The machine is fully automated and designed for linear turbulance-free test gas flow. The pressure is measured close to the sample and therefore, the correction term in the differential pressure measurement is minimized. Required amount of pressure is uniformly applied to the o-ring seals on the sample and the need for hand-tightening of the cap on the sample chamber is eliminated. Automatic addition of wetting liquid reduces test time appreciably. This sophisticated instrument has found applications in a wide variety of industries.

Accuracy: 0.15% of readingDimension: 61” H x 30” W x 26” D

Pore Size Analyzer

Cake Forming Porosity Analyzer

This is a unique instrument capable of creating filter cakes in situ on filtration media and characterizing the pore structure of the media both with and without the cake layer.

Accuracy: ±0.15% of full scalePermeability Range: 0.001 – 100 cc/min

Pore Size Analyzer

Compression Porometer

The pore structure characteristics of products experiencing considerable stress during service could be appreciably different from those evaluated in the laboratory. This award winning instrument provides a unique opportunity for evaluating the component under true service conditions.

Accurancy: 0.15% of readingDimensions: 30″ H x 19″ W x 18.5″ D

Pore Size Analyzer

Custom Porometer

The characteristics of porous material are unique and often very complex. The customer desires to test his unique porous material and measure the pore structure characteristics relevant to his applications. Therefore, a custom porometer designed to meet the specific requirements of a customer is appropriate and economical.

Compressive Stress: Up to 1,000 psiFlow Accuracy: 1% of F.S.

Pore Size Analyzer

Cyclic Compression Porometer

The instrument applies cyclic stress on a sample and measures the pore structure characteristics after a desired number of cycles. The stress cycles and testing after any desired number of cycles are automatically continued.

Accuracy: 0.15% of readingDimensions: 30” H x 19” W x 18.5” D

Pore Size Analyzer

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.

Pore Size Analyzer

Integrity Analyzer

The PMI Integrity Analyzer provides fully automated testing of filter integrity. The integrity test detects very small amounts of flow through a sample before the bubble point is reached, allowing early identification of defects, pinholes, or structural weaknesses.

Accuracy: ±0.15% of full scaleDimensions: 30 in (H) × 19 in (W) × 18.5 in (D)

Pore Size Analyzer

Nano Perm Porometer

Utmost limited deformation and damage to sample are key factors for evaluating nano size pore distribution. BET requires to freeze sample at 77K, and Mercury Porosimeter needs to add pressure up to 60,000PSI. In contrast, nano-permporometry can measure by minimum differential pressure and from humid and dry environment. NPP realized measurements for hydrophobic and hydrophilic samples with using precise controlled water vapor and hexane vapor gases.
