 Test Time: Test Time: BET multi-point method can test four samples at the same time, the test and the average speed for each sample point for each determination of partial pressure for about 5 minutes total for each sample with an average of about 30min; BET single point method while test 4 samples measured for each sample tested and the average speed for about 5 minutes; solid standard sample reference method to test three samples while the average time for each sample measured about 6 minutes abroad, only a quarter of similar equipment test time; more of these tests Time does not include pre-purification sample purge time. 
 Purge processing: with the only integrated degassing device (non-split), to solve the degassing, test integration, to achieve the sample in situ treatment with a single installation, with zero contact with air to ensure that the sample the efficiency and effectiveness of pretreatment; 3H-2000A 
 Thermal Aid of wind: wind-heat with the only help de-program-controlled device, guaranteed fast sharp desorption peak, reducing the background error; 
 Quantitative management program-controlled switching: a program-controlled six-way valve is the only calibration system, the action cycle of less than 10 milliseconds; and to quantify the volume control program-controlled switching; 
 Inhibition of zero-drift detector: the only detector with a constant temperature system, the detector is less than 0.1mV 10min drift test results to ensure the accuracy and stability; 
 Concentration of chromatography: the only chromatography with nitrogen partial pressure detection system, the relative flow method accuracy by 10 times, the nitrogen concentration of control accuracy and precision are up to ten thousandth, high stability; 
 Size model estimation: Estimating size with the only data processing functions, and gives size estimates report; this function is given according to the specific surface area of each model, the average particle size, particle shape on to play a guiding researchers to determine effect; 
 Gas Purification cold trap: the only gas purification with a cold trap so that the number of gas purity level and above increased by 1; 
 Gas source switching protection: the only gas source switching with instructions and protection devices, breathe off automatically expire permanently avoid misuse charged for damage to the detector; 
 Purge time: purge with the only timing, timing accuracy of 1 second. Countdown to automatically cut off after the heating power, and voice prompts; 
 Temperature monitoring: monitoring of elimination of liquid nitrogen temperature of liquid nitrogen temperature difference between the impact of general industrial use broad; room temperature monitoring the elimination of environmental temperature. 
 Test Accessories: standard high-purity He, high purity N2 gas mixture of nitrogen and helium 3 bottles of gas average gas use for longer than 2 years; Shanghai Branch Jie sample tube to ensure the accuracy of the test tube also makes the kind of convenience sample is not limited to powder samples in the test; 3H-2000A 
 Control system: automatic process control adsorption and desorption process of various important aspects of voice prompts; equipment operator for the operation of other work or leave, do not worry delayed test; 3H-2000A
