Features
Test principle: dynamic nitrogen adsorption specific surface area tester, using gas chromatography , cryogenic adsorption principle .
Measurement range : 0.1m2 / g ~ 3500 m2 / g
Test accuracy: measurement error ≤ ± 1% ( national standard )
Test method: When the sample tube immersed in liquid nitrogen , the nitrogen gas mixture adsorbed by the sample , then the sample tube leaving liquid nitrogen adsorbed by the sample desorbed nitrogen , adsorption and desorption based on the response curve can be calculated by specific surface area of the sample measured . Tested fully functional, with a single point test , comparison test , multi-point (BET) 3 different ways to test . Rugged and reliable instrument , no special requirements on the use of the environment , the data is stable and reliable . Simple operation and easy maintenance.

Test time: one sample per measurement takes five minutes each time to test a sample .
Analysis Software : In Windows XP systems running the software fully functional, easy to make comparative analysis of the test results , test results can be displayed to save or print .
Power supply : AC220V ± 10% 50Hz 300W
