Brief introduction Independent intellectual property rights, the function of BET is more than the surface, can replace the import; BJH can be obtained from the adsorption curve of the pore size distribution, the test time can be saved by half; The degree of automation is high, can be completely unattended; Unique vacuum and gas path design, the use of a unique built-in micro control valve; Reliable leak free (10-9cc/sec) - free vacuum system; High stability high sensitivity pressure sensor (0.25%); Complete automatic control and balance technology of relative pressure balance time; Software functions are complete, the whole experiment on the computer screen real time display, test results synchronization; Only with high purity nitrogen, no helium; High quality liquid nitrogen dewar and sealing device, greatly reduces the consumption of liquid nitrogen; Compared with foreign imported equipment, the most competitive price; Technical parameter Work energy: Determination of BET surface Langmuir specific surface BJH pore size distribution, total pore volume and average pore size were determined by adsorption curve. Working gas: high purity nitrogen (no helium) Nitrogen partial pressure: 0.35 ~ 0.01 ~ 0.995 Limiting vacuum degree: 6.8 x 10^-2Pa Pressure precision: 0.2% Pretreatment: parity Test range: surface ≥ 0.01M^2/g, no limit Pore size 1 ~ 300nm Measuring accuracy: ≤± 2% Test efficiency: single test BET surface 30 minutes Determination of pore size distribution from the adsorption curve for 3 hours Operation mode: automatic Soft parts: Special
