G400 Gas Mixing Systems


G400 Gas Mixing Systems can provide any gas mixture with up to 9 different gases. Gases are mixed automatically using Mass Flow Controllers with superb accuracy.  Our PC-based MFC Gas Mixing Software (C960) performs all the calculations required to generate your chosen gas mixture and implements mass flow controler settings with a mouse click. User may mix one gas combination and queue the next. If any selection is out of range the software warns the user.  Contact QUBIT with your specific requirements.  Let us know a number of gases, types of gases being mixed, concentration ranges of resultant gases and the total final flow rate required, and we will design your Gas Mixing System.
