China Automatic Nitrogen Adsorption Specific Surface Area Analyzer Tester

SA-2000A automatic nitrogen adsorption specific surface area tester is currently unique and fully automated surface area tester equipment for testing a number of features in domestic ,it is widely used in graphite, batteries, rare earth, ceramics, aluminum, chemical industry and universities powder materials research and development, production, analysis, monitoring link.
♦ * programmable six-way valve calibration system, the operation period is less than 10 milliseconds, the only domestic quantitative pipe volume programmable switching function;
♦ have only domestic heating purge; solve the degassing, testing integration issues, to achieve a sample situ treatment with a single installation, zero contact with air, to ensure the efficiency of sample pretreatment and effectiveness;
♦ purge program has a timer function, automatically cut off heating power after the countdown is complete, and voice prompts;
♦ * has the only nitrogen partial pressure chromatography detection system, the detection accuracy of the only reached 0.01%;
♦ has a domestic first and only program-controlled wind-heat removal system to help ensure fast get sharp desorption peaks, reduce background error;
♦ have the only cold trap gas purification function, so that the purity of the gas more than 10 times;
♦ has a domestic first and unique thermal conductivity detector temperature control system, the detector 10min drift test less than 0.1mV, to ensure the accuracy and stability of the test results;
♦ has a particle size in the only model to estimate data processing capabilities, and gives the estimated size report; this feature can give the average particle size based on the specific surface area of each model, for researchers determine particle morphology play a guiding role;
♦ * has the only liquid nitrogen temperature monitoring function, the elimination of general industrial liquid nitrogen temperature differences affect, broad conditions of use;
♦ have the only source of gas detector switch indicates the protection device, automatic power breathe, breathe live permanently avoid damage to the misuse of the detector;
♦ instrument parameters 5 inches large screen LCD display, various mechanical parts of the operation instruction, the instrument working state parameters of software, hardware also showed that even if the software is not open instrument can also accurately grasp the state, making the instrument a higher degree of stability;
♦ sample tube, sample loading, easy to clean, to ensure test accuracy while making the kind of convenience sample tubes is not limited to a powder sample testing;
♦ adsorption-desorption process of automatic process control, all important aspects of voice prompts; instrument operation the operator to do other work or leave do not have to worry about delays experiment;
♦ software self-developed high-precision data processing systems, high sampling frequency 100Hz, automatic control; having a functional surface area data processing capability; USB communication interface;
(Above with "*"are features which No. SA-200BET-A has but SA-2000A does not have)
