Test ranges:0.0005 (m2/g)~no known upper limit (specific surface area);2nm-500 nm
Test accuracy:specific surface area repeatability error ≤±1.0%
Sample number:two samples tested at same time and two samples' degassing treatment,the sample testing system and sample processing system are independent; sample testing and sample processing can be carried out simultaneously, avoiding the contamination of the test pipeline, further ensuring the accuracy of the test and improving the service life of the instrument
Test mode:integrated "Single nitrogen test mode" and "Nitrogen + helium standard test mode", for customers to choose according to actual needs;using "Nitrogen + helium standard test mode" in line with international standards, can ensure the accuracy and consistency of results, and easy to operate;for samples that can adsorb helium at low temperature, helium gas is not suitable for determination of free space,"Single nitrogen test mode" can get the desired test results
Test gas:high purity N2gas or other (Ar, Kr are optional)
Vacuum pump:imported two-stage vacuum pump can be external and built-in; the built-in vacuum pump can be automatically controlled by the software according to the experimental needs, so as to extend the life of the vacuum pump
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
