Standard Features:

• Mix and Match modules to deliver various flow rates and gases. Liquid delivery modules are also available
• Use multiple gas mixing modules to create precicely controlled custom gas blends in real time
• Mass flow control of flow rates up to 2500 SLPM per gas; combine multiple modules for expanded gas blending and mixing capabilities
• All-digital control eliminates analog calibration requirements and inaccuracies
• Ethernet Interface for simple configuration and expansion!
• The output from multiple Gas Delivery Modules may be combined to provide dynamically controlled gas flow rates and compositions, including Stoichiometric control
• System-wide control of all Fideris Test System components using FCPower Software, LabviewTM, or other programming language 
• Integrated hardwired Run/Standby signal
• Power Over Ethernet (PoE) for redundant power
• Front panel LED status of Ethernet communications, inlet gas pressure, gas enabled, and power
• Check valves for gas backflow prevention
• Pressure regulator on inlet gas line to provide the highest degree of accuracy
