Design Features: This series of gas mixture proportioning cabinet is specially designed for high precise large flow two-element or multi-element gas proportioning. Input and output pressure of the product is adjustable and settable by itself. Thus, it can realize automatic control. It is equipped with an infrared analyzer. Consequently, the digital display of the proportioning content is more visualized and proportioning precision is higher. Technical parameters: 8300M series Output Flow: 500-900m3/h Inlet Pressure: 0.6-1.2MPa Outlet Pressure: 0.4-0.8MPa Applicable Gas: (Ar+CO2/ Ar+O2/ Ar+CO2+O2/ Ar+H2/Ar+He/N2+CO2 and other two-element gases or multi-element gases) Proportioning Range: It is arbitrary adjustable according to customers' manufacturing technological requirements. Proportioning Precision: ±0.2-1.0 % (designed according to specific constituents of gas and technological Requirements) Connection Type: Stainless steel flange plate Boundary Dimension: 860mm×690mm×1660mm
