Product Description
Low-Flow Gas Mass Flow Controller for Precision Process Delivery
The Series GFC Model GFC-2133 Gas Mass Flow Controller is engineered for applications requiring tight regulation at lower flow rates up to 50 LPM. Its straight-tube thermal sensor and precision restrictor element maintain consistent performance even as upstream conditions fluctuate — making it ideal for laboratories, pilot plants, and production tools that depend on repeatable gas dosing.
Automation-ready electronics accept industry-standard analog control signals, while the integrated tiltable LCD provides real-time verification at the instrument.
