Product Description
Mid-Range Gas Mass Flow Controller for Industrial Process Systems
The Series GFC Model GFC-2142 Gas Mass Flow Controller is engineered for precise control of process gases in laboratory and production environments requiring dependable performance up to 100 LPM. A straight-tube thermal sensor works with a precision restrictor element to deliver consistent flow even as upstream pressure or temperature changes.
Designed for automation integration, the GFC-2142 accepts standard analog control signals and features a local tiltable LCD display — supporting efficient setup, diagnostics, and long-term operation in coating chambers, vacuum tools, and manufacturing gas lines.
