The 0250 Series is an innovative, reliable microcomputer-based controller providing power for up to four 829 Series Mass-Flow Controllers in a new compact design. Additionally, the Model 0254-AL  can be used to generate flow set point commands, display flow rate, totalize flow, provide blending multiple flow streams, and more. This fully RoHS compliant device has a very user-friendly interface and is offered with a table-top mount.
