Introduction Specific surface and pore size analyzer static capacity , with BET ( single point, multipoint ), Langmuir, the outer surface of the pore volume ( pore volume ) , smoking ( off ) isotherms , BJH method aspiration ( removal ) is attached mesoporous large hole diameter analysis , MP / SF / HK law pore size analysis and other testing. Imported high-precision pressure sensor (1000torr, 10torr, 1torr) and cryogenic solenoid valve control , having an outer chamber temperature real-time monitoring capabilities , the original outer chamber volume accurate testing capabilities , with imports of mechanical pumps + two turbo-molecular pumps, vacuum degree up 10-6Pa. The new multi-functional software operating system that supports Windows 7 / XP systems , ultra- high-speed LAN port connection . The instrument also have the true secret Features 1. The independent design, domestic unique stainless steel channel parallel vacuum line system, vacuum pumping speed adjustment valve system patent technology, has realized the smoke slowly, almost sobbed speed of automatic adjustment, the adjusting range is 2-200 - ml/s; 2. Standardization, modular cavity without leakage container type design, the most effective reduce the external air chamber (manifold) dead volume, and the external air chamber with air inlet and exhaust tube road system is completely isolated, greatly improving the instrument of performance, to achieve the best control system; 3. The system adopt imported heating solenoid valve control, eliminate the error of measurement, introduced the electromagnetic valve body fever, fast response speed, but also effectively solve the electromagnetic valve control may cause reverse leak problem, cleverly designed, technology only. 4. High precision temperature sensor in real time, accurate determination of the internal temperature of the dead volume, and in real time calculation of gas adsorption is introduced into the calculation, greatly improving the accuracy of test results, accuracy and stability, domestic leading technology, reached the international advanced level. 5. Using helium free space to cold automatic accurate measurement, measurement technology fully in line with international standards and national standards.At the same time, in 2012, my company independent development of new technology, "quality input method" can measure the free space, need not helium test results completely meet the standard requirements, technical level of domestic first, reached the international advanced equipment level; 6. "vacuum interlayer constant liquid level control integrated technology" domestic original, completely equivalent to the isothermal clamp technique; 7. At first the "external splash proof system" and the perfect combination of "bench" splash proof control procedures, can effectively prevent the ultrafine powder fly caused by pipeline, valve, pressure sensor and other important components of pollution, effectively reduces the maintenance cost of the instrument; 8. "Pcd/Pd balance of domestic initiation pressure intelligent control act" patent technology, at the same time created the test pressure set 6 section optimization method, can set pressure range between 0.1 133 kpa, flexible configuration, realize the precision test, the highest pressure automatic adjustment, make the whole testing process intensification, rationalization, efficiency, and control technology in domestic to lead; 9. P0 system design is unique, innovative, rationality, stability and real time; 10. "molecular pump" and "multi-stage pressure sensor of smooth connection" technology, the only at home, a complete set of testing system of vacuum degree is as high as 10-6 pa, fully meet the 0.35 nm or more holes, amd and precise analysis, reached the international advanced equipment level; The new design, look pleasant, professional and high-end multi-functional micro analyzer , humane choices, selling products at home and abroad ! Technical Parameter 1 Principle method: gas adsorption, static volumetric method; 2 Test function: isothermal stripping absorption curve;Single point, multi-point BET specific surface area;Langmuir specific surface area;Surface area (STSA);A single point of adsorption total pore volume and average pore diameter;BJH mesoporous large distributed volume and pore size distribution analysis;T - the plot, the as - plot, DR, MP microporous routine analysis;HK, SF, microporous precise analysis; 3 The average particle size estimation;Special features: 4 NLDFT pore size distribution analysis;True density precision
