GF120C-908811 is a configured Brooks Instrument GF120 Series metal-sealed thermal mass flow controller observed in Sonisys auction records as a nitrogen / N2 unit with a 10 SCCM range. Brooks GF100-family documentation covers GF120 and related GF-series models as high-purity and ultra-high-purity thermal mass flow controllers and meters for semiconductor, MOCVD, and other gas flow control applications that require an all-metal flow path. Exact gas calibration, flow range, valve state, fitting package, communication interface, seal package, and process options must be verified from the physical unit label and configuration documentation
Configurations vary. Verify the exact unit before choosing a replacement.
