Product Description

P0 test: an independent vapor pressure (P0) test stations, to ensure high accuracy of the partial pressure of the test;
Sample preparation: number of samples processed simultaneously: 2/2/4 pcs; two-way degassing station has an independent temperature control, and an independent timing, at different temperatures and at different times of the sample degassing treatment can support and test carried out simultaneously;
Sample preparation mode: having the domestic unique "conventional heating vacuum molecular diffusion mode" and "molecular replacement mode" in two optional features; molecular replacement mode molecular diffusion model efficiency by more than 1 times, can save more than half of the pre-treatment time to solve the conventional sample preparation method static problem a long time;
Stress Test: Stress Test Range 0-1.6bar (0-160KPa), accuracy error ≤0.15%;
Liquid nitrogen level control: a liquid nitrogen holding surface servo system, the elimination of the testing process because the liquid nitrogen so that nitrogen volatilization surface changes brought dead volume change, improve test accuracy;
Atmospheric recovery: a leading domestic and international testing, degassing is completed automatically restore normal pressure function for easy removal, anti-splash sample;
Intelligent self-checking system: The instrument has a self-test hardware and pneumatic tightness self-test function, can automatically detect the sample tube is installed, the jacket tubes are tightened, and check to make sure the location of the leak, given text prompts and voice prompts;
Voice prompts: a unique intelligent real voice prompts; 
Software interface:
 1, graphical control interface: pro and control and monitoring interface, complex instruments work in the form of a state diagram to show that the instrument work status at a glance, and the structure of the various valves, vacuum, nitrogen Cup lift All hardware, operating temperature, etc., pleasing;
  2, custom style conversion: style software interface can be converted to the user's preferences;

Control System: 
   1, strong and stable control system to prevent accidents; instrument with real-time data storage function and status, in the long run the process automatically, even when the data line is disconnected, unexpected power outages and other unforeseen circumstances, it served as the instrument to restart and then can be restored test data into the test process continue testing;
   2, when the cup of liquid nitrogen at the top, if not decline in liquid nitrogen and vacuum cup, the temperature rises, the gas adsorption quickly overflow the sample tube, so that the risk of sample tube burst; SA-2000PS series instrument has a leading domestic intelligence and security liquid nitrogen Cup "safe drop" control systems to prevent accidents, the key point of the system is that the operator cannot be controlled at the liquid nitrogen cup drop, even when unexpected power failure or restart the device, the device automatically enters the liquid nitrogen Cup "security drop "process;
   3, at home and abroad leading pump start-stop management system, during the test has been running without a vacuum pump to reduce noise and prolong the life of the vacuum pump;
   4, the operation of the instruments detailed logging; the instrument run logs automatically record the results of each command and the instrument in the instrument during the operation, including the switching valve, pump start and stop, the original acquisition data, accurate to the second time. The log for the reliable operation of the instrument to provide protection and after-sale;
Data processing  
   1, isotherm analysis has a standard mode, fine mode and custom modes, aperture can be set request for key segments for fine analysis;
   2, custom testing process: test can be adsorbed, adsorption-desorption tests, and directly into the desorption test (automatic rapid adsorption saturation);
   3, a variety of options to test the theory, there is a chart graphs, histograms;
  4, a powerful data management and processing system: the raw data and the calculation of all the test results are stored as SQL database support by date, operator and sample names, etc. Find filtering capabilities; support for bulk export;
