Vacuum system：stainless steel micro welding vacuum pipeline system，the vacuum pipeline is connected with all-metal VCR, which can minimize the dead volume space of the pipeline and maintain high vacuum for a long time；vacuum leakage rate up to1x10－10(Pa*m3/s)

Partial Pressure:P/Po controllable accuracy range is 10-4-0.998

Pressure measurement：theoriginal imported high-precision silicon film pressure sensor measures the pressure, which significantly improves the test accuracy，2 pcs 0-3 Bar（0-2250 Torr），pressuresensor can be provided with import inspection certificate; After the performance upgrade, the resolution of the high range pressure sensor is enhanced from 4 Pa to 1 Pa, and the pressure reading resolution is increased by 4 times，significantly improves the balance precision of adsorption saturation or desorption saturation, so as to improve the accuracy of test results and credibility

Pressure accuracy：the original imported high-precision silicon film pressure sensor’s accuracy is 0.15% of the actual reading, better than 0.15% of the full range

Pressure reading：pressure sensors in all ranges use RS485 or RS232 communication to read pressure values; compared with the traditional acquisition module for analog pressure data collection, the accuracy of digital pressure data collection is higher

Control system：pneumatic valve control system with high integration and anti-interference ability, improve instrument stability and service life

Calibration gas：the optional use of He gas for cold free space volume calibration function，not only the "nitrogen

+ empty tube" mode can be used to calibrate the cold free space

Protective measures：transparent plastic safety door can not only protect the safety of experimental personnel but also prevent the error and even interruption of experimental data caused by human error collision of liquid nitrogen cup and sample tube

Liquid level control：EASY-V’s original liquid nitrogen level control system ensures that the liquid nitrogen level remains unchanged relative to the sample tube during the whole test process, completely eliminating the measurement error introduced by the change of cold volume space

liquid nitrogen bottle：imported 4L stainless steel inner Dewar bottle is durable and not easily damaged，can be tested continuously for 72 hours without adding liquid nitrogen under the condition of no need to add insulation cover, which can fully meet the requirements of long-term testing of pore size

Date processing：Windows compatible data processing software has perfect functions and easy operation，multi

- mode data analysis, graphical data analysis results report
