\n\tMeasurement of true density, porosity,<\/span><\/font> percentages<\/span><\/font> of open-cell \/ closed-cell  of foams plays important role in 

\n\tdevelopment and quality control of various properties of the cellular materials. Characterization of foams presents 

\n\tits own challenges and the highest performance gas pycnometers and dedicated accessories need to be used.<\/p>\n

\tThe enhanced and optimized HumiPyc Gas Pycnometers with dedicated hardware are superior tools for foams 

\n\tcharacterizations.<\/span><\/font>\n<\/p>\n

\n\tDesign features:<\/span><\/font><\/p>\n

\t–  Fully automated operation via PC
\n\t–  Novel software approach  for experiment design and convenience of operation
\n\t–  Ability to set low pressures to avoid foam distortion and carry out accurate measurements using 24-bit resolution
\n\t–  True gas purge using a separate exhaust (similar design as in the cement density and fineness  (specific surface area)
\n\tdetermination technique <\/span><\/font>( Permeametry)<\/span><\/font><\/a>
\n\t–  The foam sample can be purged to specific relative humidity value using optional RH probe.
\n\t–  Specific (optional) hardware for other analytical capabilities<\/span><\/font>\n<\/p>\n

\n\tStandard test methods for foam open cell <\/span>content, like ASTM D6226 or ISO 4590 <\/span>stipulate specific shapes and sizes of foam <\/span>samples.<\/span>

\n\tTo optimize the foam volume determinations <\/span>results,  volume reducing adapters accepting <\/span>cubes or cylindrical shapes can be provided.<\/span>\n<\/p>\n

\n\tTo reduce errors in determination of <\/span>physical  volume measurements of a <\/span>foam sample, additional hardware for <\/span>cutting exact shapes can be provided.<\/span>\n<\/p>\n
