Sorption gas: N₂ (high purity); Ar, Kr, CO₂, CH₄, etc. available

Analysis No: 2 samples tested alternately

Sample Type: powders, granules, fibers, flakes and other materials

Pressure Sensor: 1000torr (133kpa), 10torr (1.33kpa); 1torr (0.133kpa) or 0.1torr (0.0133kpa); pressure accuracy ≤± 0.15%（P.S）

P0 tube: there is a separate P0 tube in every analysis port, two in all, controlled by a separate pressure sensor, completely separates from the analysis bit, real-time detecting the nitrogen saturation vapor pressure, and participating in the theoretical calculation; also the atmospheric input method to determinate the P0 accurately;

Cold trap tube: sample degassing system has a special cold trap device that can effectively remove the water, hazardous substances and other impurities, degassed from the special sample, and it can avoid the contamination of the vacuum system;

Degassing system: two samples can be analyzed simultaneously, also can be degassed in the original port; another with two separate sample degassing station, which is independent and separate from the sample analysis. Throughout the degassing system, there are two independent heating packages, two independent temperature control systems, which can be programmed by temperature control; you can choose another four external vacuum degassing pretreatment system;

Degassing temperature: room temperature -400℃, accuracy ± 1℃;

Test Efficiency: multi-point BET surface area--30 minutes per sample; Determination micro pore size distribution from adsorption and desorption isotherms_5-20h per sample.
