Feature

2 pretreatment sample degassing stations, 1 sample analysis station, 1 P0 test site, 2 independent cold traps;
Degassing system and analyzing system independently operate;
Automatically and intelligently test without manual guarded, friendly voice prompt;
BEST manifold module, ensure the vacuum and stability;
Independent high-precision saturated vapor pressure (Pₒ) real-time test station;
Saturated vapor pressure spiral Pₒtube: spiral Pₒ tube connected with the instrument host, obtain the liquid Nitrogen temperature faster, making the tested saturated vapor pressure closer to the real value;
Double cold traps to protect the vacuum system and molecular pump;
Filter bag developed independently by BSD Instrument, eliminate the pollution from internal structure of the instrument;
Degassing: 2/4/8 optional pretreatment ports, fully automatic program control, timed start, automatic start and stop of vacuum pump, programmed temperature heating, timed end;
Intelligent self-test process, intelligently judge whether sample tube installed, tube jacket tightened and gas leak or not;
Automatic capping: Effectively reduce the volatilization of liquid Nitrogen;
Detailed instrument operation log display and record, can be accurate to the second, the whole experimental records can be traced.
Prevent accidental “safe fall” intelligent control of liquid nitrogen cup, completely avoid the gas expansion and the danger of sample tube burst because accidental fall of cup;
Intelligent dual-mode gas injection control, improve the experimental efficiency under the premise of guaranteeing the experimental precision;
Independent 4 gas pipelines inlet;
Large-capacity and small-diameter Dewar, keep warm for more than 140 hours, no need to add liquid Nitrogen for 96 hours of continuous test;
Dual-station microporous test function (Optional);
Multi-component competitive adsorption IAST theoretical model;
Pressure sensor: more than 2 pressure sensors for each test site, test accuracy better than ±15%, resistant to sulfur dioxide, ammonia and other corrosive gas;
Gas pipeline joint: VCR hard connection and corrosion resistant;
Pretreatment: pretreatment temperature range from room temp to 673K (400 centigrade), 0.1 centigrade temp control precision;
Vacuum system: equipped with two-stage mechanical vacuum pump and molecular pump, molecular pump pressure can reach 1E-6Pa, make sure P/Pₒreach 1E-8;
High-quality gas control valve and solenoid valve combination, eliminate gas thermal expansion because of heat generation caused by single solenoid valve;
