Introduction:
The MT-200A Series Gas Mixing Proportioner uses the principle of precise control of gas mass flow. The gas flow of each component is precisely controlled and mixed by the sonic nozzle principle without being influenced by the ambient temperature and the pressure of the gas source.
Complete product range, from 2 to more than 10 kinds of standard gases mixed at the same time, choose to connect directly to the computer and the use of touch screen in two ways to set the display, simple operation, performance and competitive prices, a wide range of applications. It can be widely used in gas concentration sensor calibration, semiconductor and specialty materials research (CVD), plasma etching, desulfurization and denitrification, welding, atmosphere preservation, sterilization, medical and microelectronics industry mixed gas preparation, the main target is large Secondary schools, laboratories, research institutes and high-tech enterprises engaged in the research and development of gas analysis instruments and gas detection. Features:
1 Adopting high-precision mass flow controller with high gas distribution precision and short time with stable gas concentration, the accuracy of mass flow controller is 1% FS, repeatability is better than ± 0.2% FS and the linearity is better than ± 0.5% FS Custom higher accuracy);
2 can be prepared at the same time 2 to 10 kinds of standard gas, with multi-range function, the user can choose the appropriate full-scale;
3 Dilution ratio range, can be diluted from one part per million to 100% to meet the gas concentration sensor calibration needs
4 ratio of a stable concentration of gas time is short, greatly reducing user test time and gas consumption
5 pipeline systems are used standard 316L stainless steel parts, with anti-corrosion ability, the corrosive gases and toxic and harmful gases can be equipped with gas; and are used to connect the dual card sets, air tightness;
6 all-digital man-machine interface control mode, simple, easy to operate, the system's working status at a glance in the software interface;
7 standard RS485 communication interface (optional), with the computer to achieve two-way communication.
8 air filter, the product of the intake pipe are installed within the high-performance 316L stainless steel filter, can be very good to avoid the gas source of particulate pollutants into the pipeline damage.
9 to prevent the gas back to the gas path of this product is also equipped with 316L stainless steel check valve to ensure unidirectional gas flow, gas reflux will not cause damage to the instrument.
10 high efficiency and uniform gas mixture, the product uses the principle of sonic nozzle so that each branch into the gas quickly and evenly mixed. Technical Parameters :
