Embedded test computer, safe and stable. 10-inch capacitive touch screen, tablet control experience.

The ball screw integrated lifting system, controlled by the stepper motor, overcomes the shortcomings of common screw types easy to jam, and so on.

The protective safety door can prevent safety accidents caused by accidental contact with low-temperature liquid nitrogen and eliminate the impact of environmental factors on the test.

4L stainless steel inner Dewar bottle overcomes the fragile defect of glass Dewar bottle, and high thermal insulation ensures continuous test requirements for more than 72hrs.




Digital pressure measurement and data acquisition system

  • The pressure and temperature sensor with digital output has twice the accuracy of similar products with analog output and stronger anti-interference ability.

  • Industrial standard RS485 or RS232 communication mode. Sensors are added on demand on the communication bus, with high scalability.

  • The high-precision digital pressure sensor has a pressure output resolution of 1Pa, which is conducive to higher testing accuracy compared to the 4pa resolution commonly used in the same industry.

Key Performance Indicators


> Test function:


▪ Static volumetric principle, adsorption/desorption isotherms measurement, single and multi-point BET method, Langmuir method, BJH total pore volume and pore size distribution analysis, DR and DA filling theory, t-plot external surface area measurement, true density measurement; Powerful online data analysis system and specific surface area and pore size distribution test system to ensure more stable and accurate test data.


> Test ranges:


▪ 0.0005 (m2/g)~unknown upper limit (specific surface area); 2 nm - 500 nm.


> Test accuracy:


▪ Specific surface area repeatability error ≤±1.0%.


> Sample number:


▪ Four samples were tested at the same time and the four samples' degassing treatment (optional), 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 modes:


▪ Integrated "Single nitrogen test mode" and "Nitrogen + helium standard test mode" for customers to choose according to their actual needs;
▪ The "Nitrogen + helium standard test mode" in line with international standards can ensure the accuracy and consistency of results, and is easy to operate;
▪ For samples that can adsorb helium at low temperatures, helium gas is not suitable for the determination of free space. The "Single nitrogen test mode" can get the desired test results.

Sample Degasser Introduction



▪ Flexible heating of samples between 25°C (77°F) and 400°C (752°F) depending on the different sample processing requirements; Sample degasser can remove moisture from the sample for drying function.
▪ During sample heating, the treatment system can be optionally evacuated to effectively remove impurities adsorbed on the surface of the sample particles and achieve a cleaner treatment of the material.

▪ For samples that should not be in contact with air, a protective gas can be injected during the processing as needed to achieve complete isolation of the sample from the air.

▪ After the sample treatment, the protective gas is passed into the cooling process to realize the isolation and protection of the treated sample.

▪ For samples with more moisture and impurities on the particle surface, the protective gas can be injected by the action of airflow to achieve the function of purging the sample surface, which is conducive to the faster and more thorough removal of impurities and moisture.
