Technical characteristics:
 
Completely independent bi-station parallel analysis, can simultaneously carry out pore size analysis of two samples and degassing treatment of two samples, and the test efficiency is high;
The instrument is equipped with two ectopic degassing stations, and the analysis station has the same degassing function and humanized design; High desulfurization temperature 400 ℃;
Bistatic multi-point BET specific surface test can be completed automatically within 30 minutes;
Adopt liquid nitrogen surface control integrated system and software compensation technology to ensure that the non-uniform temperature field in the sample chamber is relatively constant during the whole test process, so as to ensure the accuracy of analysis, which is suitable for various cold baths such as liquid nitrogen, liquid argon and ice water;
Equipped with 3L large-capacity vacuum glass liner Dewar bottle and liquid nitrogen volatilization prevention unit to ensure that the experiment can last for 72 hours;
Self-control adjustable multi-channel parallel vacuum pumping system, built-in anti-splash unit and "step-by-step" anti-splash program effectively prevent ultrafine powder from pumping and completely avoid instrument pollution;
