BET surface area, pore size distribution : Automatic specific surface area/pore size distribution measurement instrument


  • High precision measurement at 1.5x throughputSimultaneous measurement of up to 4 specimens and high precision simultaneous measurement of 3 specimens.
  • Measurement time is significantly shortenedThe dedicated exhaust valve and improved software greatly reduces measurement time.
  • Equipped with GDO* functionality [NEW]Speedy measurement with optimum amount of gas dosing based on adsorption isotherm data from previous sample measurement.
    *Gas Dosing Optimization
  • Automatically measures adsorption isotherms according to minimum condition settingsCapable of measuring adsorption isotherms of the first sample with minimum condition settings.
  • Equipped with AFSMTM for increased measurement precision and reproducibility(Domestic patent: #3756919 / US Patent: 6,595,036)
    The adoption of Advanced Free Space Measurement (AFSMTM) has resulted in improved measurement accuracy and reproducibility.
  • Adsorption isotherm measurement of various gases over a wide range of temperaturesThe gas selector and various temperature devices allow adsorption isotherm measurement of various gases over a wide temperature range.
  • Progress of measurement can be monitored on software. [NEW]The progress status of a measurement can be checked at a glance, improving working efficiency of measurers.
  • Improved operabilityThe slide and latch mechanism allows easy attachment/detachment of temperature devices such as Dewar vessels.
  • Improved maintainabilityImproved maintenance software enables monitoring of the performance of each part.
  • Smallest, most lightweight implementation in the world [NEW]The selection of optimum materials has resulted in the world's smallest and most lightweight instrument.

Conforming to JIS Z8830, Z8831-2, K6217-7 and ISO 9277, 15901-2, 18852.
