GF125C-845022 is a configured Brooks Instrument GF125 Series metal-sealed thermal mass flow controller observed in Sonisys auction history and external inventory references. The local auction record identifies a Brooks GF125CXXC mass flow controller with AR 2000 SCCM and SH45 wording. External inventory references also associate GF125C-845022 with Celerity and SiH2Cl2 500 SCCM wording. Because the archive coverage is sparse, all gas, range, calibration, interface, fitting, and valve details should be verified from the physical unit label
Configurations vary. Verify the exact unit before choosing a replacement.
