Brooks Instrument GF040CXXC-00157 Mass Flow Controller

The Brooks Instrument GF040CXXC-00157 Elastomer-Sealed Mass Flow Controller (GF040 C) uses thermal-mass flow sensing to measure and actively regulate gas flow, designed for multi-gas operation with Brooks’ MultiFlo gas database. It covers a flow range from 3 sccm to 50 slpm, delivers 1% of set-point accuracy, and features a sub-1-second response time to support fast, dynamic control across varied gas mixes. The GF040 C variant operates up to 150 psi with an ambient temperature range of 5°C to 50°C and uses an elastomer-sealed, normally closed valve configuration, making it suitable for lab and process environments that frequently switch gases or re-range without sacrificing measurement precision.
