Features 1) The original cartridge piping systems integration , the use of imported container line , significantly reducing pipeline connection point , greatly reducing the leak rate and improve the ultimate vacuum ; Less 2 ) modular design , integrated container line , the need to manually connect the components , which will help with the maintenance of the configuration according to user needs and post- upgrade ; 3 ) Germany imported double -stage vacuum pumps, low noise and stable operation, anti-oil back to functional excellence , extreme high vacuum, up 4x10-2Pa (3x10-4Torr). 4) using widely used in industrial control systems , programmable controller solenoid valve control system , anti-interference ability , stability is greatly improved, installation and removal is very convenient; 5 ) The unique design of the test system and the sample line tubing separation structure effectively prevents the impurities generated in the process of sample contamination on the test pipeline . 6 ) Using the same brands of similar products imported high-precision silicon thin film capacitive pressure sensors, pressure measurement accuracy of 0.15% corresponding readings , far better than 0.15% of full scale accuracy (FS) sensor ; 7 ) using eight 0-1000Torr (0-133Kpa), 4 0-1Torr (0-0.133Kpa) pressure sensors, pressure within the test range of segmented measurements, greatly reducing the measurement error under low vacuum , 0 -1Torr silicon thin film pressure sensor accuracy is much higher than the same resistance range Pirani vacuum gauge (usually error of 10% -15 % ) ; Technical Parameters Measuring range : 0.0005 (m2 / g) - to no upper limit (specific surface area ); 0.35nm-2nm ( micropores ), 2nm-500nm ( the holes and big holes ); 0.0001cc / g-- to unlimited (total pore volume ) . Accuracy: Repeatability specific surface area of ≤ ± 1.0%, the most probable pore repeated deviations ≤0.01nm, the true density of ≤ ± 0.04%; the outer area of ≤ ± 1.5%. Level Control : V-Sorb original liquid nitrogen surface control system to ensure full test sample tubes in liquid nitrogen surface relative position remains unchanged , the complete elimination of measurement error due to dead volume changes introduced . Data collection: the use of mainstream storage systems and high-precision data acquisition and highly integrated data acquisition module, the error is small , strong anti-interference ability . Number of samples : 4 samples can be analyzed simultaneously and four samples degassing treatment , the test samples and sample processing system independent of the system is necessary , and the sample required for the test and sample a degassing treatment can be conducted simultaneously , to avoid the contamination of the test line , thereby further improve the instrument to ensure the accuracy and service life tests. Control system: PLC solenoid valve control system , high integration and anti-jamming capability , improve instrument stability and service life. Pressure measurement : A multi- branch imports of silicon thin-film capacitive pressure sensor for pressure measurement segment significantly increased at low P / Po -point precision, 8 0-1000Torr (0-133Kpa), 4 0-1Torr (0 -0.133Kpa), a pressure sensor must provide import test certificate . Pressure accuracy: imported high-precision silicon thin film capacitive pressure sensor , an accuracy of 0.15% of the actual reading is better than 0.15% of full scale , well above the resistance Pirani vacuum gauge accuracy ( typically error of 10% -15 %). Vacuum : Imported bipolar vacuum pump can achieve external and internal instrument two kinds of placement , the pump must be built into the instrument, the software can be automatically controlled according to the experimental pump start and stop, thus extending the life of the vacuum pump . Instrument Specifications : Dimensions : length 70 × width 70 × high 85 (CM); Weight: 60 kg ; Voltage : AC 220V; Current : 5A.
