Surface Area and Pore Size Analyzer Pore Size Measurement Instrument Surface Area Analyzer
1.Product introduction
The GA 100 Series can accurately produce surface area and pore size results of powder materials. According to the different test functions, this series of instruments are divided into three types, there are A, B, and C, the C type is configured with 1 torr or 0.1 torr high-sensitive pressure sensors and turbo molecular pump with ultimate pressure of 10¯8 Pa, it can effectively take microporous analysis of microporous materials such as molecular sieve, catalyst, activated carbon, and other microporous materials.
