Product Description
Precision Gas Mass Flow Control for Automation-Driven Systems
The Series GFC Model GFC-2143 Gas Mass Flow Controller delivers tightly regulated gas flow for laboratory and industrial processes operating up to 200 LPM. Using a straight-tube thermal sensor paired with a restrictor flow element, this controller maintains repeatable performance even when inlet pressure and temperature fluctuate.
Built for integration into automated process equipment, the GFC-2143 accepts industry-standard analog signals and provides real-time feedback through a tiltable LCD display — making it ideal for coating chambers, vacuum systems, and production gas lines.
