I would like to briefly point out a few unique features.
1. Our control panels used with the Permometer Constant Volume Device will give faster results than are possible with any other system!
2. Permeability Cells: Due to a different positioning of the chamber ´O´ rings, our cell will disassemble and assemble faster than other makes. Geotest perm cells are the only standardly available cells that actually conform to ASTM D5084 paragraph 5.4.1. Specimen height change can be easily monitored during any phase of the test as the spring loaded pin always stays in contact with the upper platen. Heavier cell walls assure greater safety and higher pressure ratings.
