Degassed Situ treatment, 2 samples can be set temperature and time individually; temperature: room temperature -500℃; external pretreatment machine can be selected.

Theoretical calculations: according to the principle of the static volumetric method, we create a new method of determining cold free space, switching helium / nitrogen automatically. It achieves the temperature real-time measurement and correction, ensuring the reliability of the amount of nitrogen adsorption; through proprietary technology, it can get into the nitrogen adsorption measurements directly for certain samples, improving the test efficiency greatly.

micropore test: the test system includes molecular pump. the vacuum reaches 10-6Pa, and it can fully meet the requirements of testing micropore size distribution; adopting 1000Torr 10Torr 1 Torr, the above three pressure sensors, grading tests, mutualseamless connection, so the test accuracy, especially in low pressure, the resolution can reach 0.003Pa;

control accuracy: the multiple parallel vacuum design; the speed of vacuum pumping can be adjusted from 2 to 300ml/min automatically by original built-in fine-tuning system; the precision of pressure control has reached the international advanced level by the unique equilibrium pressure control method; The pressure controlled interval is less than 0.1KPa, and the pressure of micropore controlled interval is less than 0.01Pa, while achieving the automatic control in highest points of the equilibrium pressure, relative pressure is up to 0.998;

Liquid nitrogen surface control: eliminating the effect of the liquid nitrogen surface by integrated control method and software compensation;

 Po determination: direct determination or atmospheric pressure input method to determine Po values; it can achieve real-time monitoring and correction of Po;

The Dewar: Each sample has its own non-metallic Dewar, its insulation is greatly superior to the metal Dewar;

Automatic control circuit: international advanced self-control circuit and the data acquisition system, the Ethernet interface, greatly improves the reliability of the automatic control, anti-vibration, super anti-jamming capability. The average failure period is more than 25 years, and can be multiple, remote control;

low carbon environmental protection: the original purification device, eliminating the pretreatment impurities and removing harmful gases discharged by the vacuum pump, environmental, high analysis accuracy, walking in the forefront of the industry;

analysis software: rich physical models, intelligent analysis software, and the latest progress, such as the linear selection method of BET surface area for different materials, the database of standard isothermal line for selecting t-plot or MP analysis method for different materials; HK, FS methods for testing the microporous; also can provide CO2 adsorption (DFT method).
