PMI BET SORPTOMETER Porous Materials Inc. makes the most versatile BET Sorptometer. It performs both Physisorption and Chemisorption, with an extremely low range of adsorption pressures. Surface Area, Micropores, Mesopores, Isotherms, and Density testing can all be performed using the same testing station. Multiple testing stations are available. All tests are performed with pure gasses so no expensive mixtures are required. All tests and calibration are fully automated. Optional adsorption of vapors from high temperature liquids is available.
PMI A U T O M A T E D P O R O S I M E T E R Porous Materials Inc. makes the safest and easiest to use Automated Mercury Intrusion Porosimeter, and the only Porosimeter capable of Non-Mercury Intrusion. Everything is fully automated between placing the sample in the chamber to removal of the sample at the end of the test. (All other porosimeters require manual transfer of the sample during the test.) The PMI Porosimeter also features the least mercury exposure in the industry. Sample chambers and penetrometers are made of Stainless Steel. Systems range in maximum pressure from 200 to 60,000 PSI. CIRCLE 160 ON READER SERVICE CARD
