The PMI fully automated Advanced Bendsten Permeability & Surface Roughness Tester is able to measure air permeability and smoothness according to standards ISO 28791-2 and permeability to ISO 5636-3 and 5 with digital display.
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.
Aquapore is a liquid intrusion porosimeter used for hydrophobic pores. Water does not wet hydrophobic pores. Intrusion of water into pores occurs on application of pressure. Measured intrusion volume of water yields pore volume and measured intrusion pressure yields pore diameter
The PMI Advanced Automated Multi-Chamber Porosimeter-Permeameter has been specially designed for testing up to twelve core samples simultaneously. Core samples are held with a sleeve (pneumatic or hydraulic) which compresses the sample to the desired pressure. While the rock sample is under compressive stress, the permeability of gases are measured. This sophisticated instrument utilizes equipment that is fully automated. Execution of the test, data acquisition, data storage, and data management are all performed by the user-friendly software. Operator involvement is minimal and the robust machine requires a minimal amount of care.
The PMI Airflow Resistance Meter follows the specifications of ASTM C522-03 and provides quick and accurate resistivity values in Rayls. Air is forced through the material at required velocity or flow rate and corresponding pressure drop is measured to provide the resistivity valves.
The PMI Advanced Water Vapor Permeability Tester is able to measure the amount of water vapor a material will transmit through its structure in a specified time. The tester consists of 8 containers with water reservoirs, a standard permeable fabric cover, sample holder ring and precision drive system. Our tester should work in a conditioning room or conditioning chamber. Wet-cup can be converted to do different tests. The PMI fully automatic Advanced Water Vapor Permeability Tester conforms to standards SATRA TM 172, ISO 14268, ISO 17699, ISO 20344, NF EN 13515, and DIN 53333.
The PMI Advanced Oxygen Gas Permeability Tester is able to measure oxygen transmission rate through plastic film, sheeting, coextrusions, metals, foils, laminated film, paper sheets, other barrier sheet metals, and packages. The instrument's measurement conforms to ASTM D3985 81.
The PMI Liquid Permeameter is used to perform fast and accurate measurements of liquid permeability. PMI's Liquid Permeameter is user-friendly, features non-destructive testing, and accommodates a wide variety of samples. The Liquid Permeameter also allows testing under ambient or elevated temperatures to simulate actual operating conditions.
The PMI Advanced Gurley Permeability Tester provides fast and accurate measurement of gas permeability of solid, cylindrical and sheet samples. Featuring nondestructive testing and fast results, our tester is perfect for both R&D and quality control. The PMI fully automatic Gurley Permeability Tester is for measuring air permeability according to standards ISO 5636-3 and 5, TAPPI-T460 with digital display and pneumatic clamping.
