Test gas types: N2, and other adsorption gases CO2, Ar, Kr, He, methane (CH4), benzene (C6H6), toluene (C7H8), ethanol (C2H5OH), etc.;
P0 test: with independent saturation vapor pressure (P0) test station to ensure high accuracy of the partial pressure test;
Pressure test: original imported pressure sensor; pressure test range 0-1.6 bar (0-160KPa), accuracy error ≤ 0.15%; micro hole section pressure P / P0 can reach 1 * 10-7, points more than 50; large hole The segment has a real-time testing function of P0, so that the control accuracy of P/P0 when reaching the spiritual boundary is 0.998.
Sample pretreatment: Simultaneous treatment of sample quantity: 2; Two-way degassing station with independent temperature control, and with independent timing function, can support sample degassing processing at different temperatures and different times simultaneously with the test;
Sample pretreatment mode: It has two unique functions of "general heating vacuum pumping molecular diffusion mode" and "molecular displacement mode"; the molecular displacement mode is more than doubled in molecular diffusion mode efficiency, and can save more than half of the pretreatment. Time, solve the problem of long sample preparation time in previous static methods;
Automatic catalyst specific surface area and pore size distribution tester test efficiency: Intelligent gas injection control, medium and small adsorption sample 2-3min/divided pressure point, medium and large adsorption sample 3-5min/divided pressure point; BET multi-point method 15-30min /1 sample; BET single-point method 6-10min/1 sample; standard pore size test 60-120min/1 sample; fine pore size test 120-300min/1 sample; the above test time does not include sample pretreatment time;
Liquid nitrogen surface control: It has a liquid nitrogen surface servo-keeping system, which eliminates the dead volume change caused by the change of the liquid nitrogen surface due to the evaporation of liquid nitrogen during the test process, and improves the test accuracy;
Graphical control interface: Affinity control and monitoring interface, the complex instrument work status is displayed in the form of a structure diagram, so that the working status of the instrument is clear at a glance, and each valve, vacuum pump, nitrogen cup lifter, and temperature can be displayed on the structure diagram.
