Precision Nitrogen Flow Control with GMFC-CXB-4-R4-D-A1-F3 Mass Flow Controller
In industrial and laboratory gas systems, accurate flow control is not a luxury—it is a requirement. Whether you are purging a pipeline,
calibrating a sensor, or maintaining a controlled atmosphere, even small deviations in gas flow can affect product quality, process safety,
and experimental repeatability.
The GMFC-CXB-4-R4-D-A1-F3 gas mass flow controller is engineered to meet these exacting demands, delivering reliable, repeatable
nitrogen flow control across a wide operating range.
Built for Nitrogen Applications
This mass flow controller is calibrated specifically for nitrogen (N₂) and supports a flow range of 1.2–60 SLM. That broad span allows a
single device to handle both low-flow fine-tuning and higher-flow process requirements, reducing the need for multiple controllers in one system.
