GF80 Series Metal Sealed Thermal Mass Flow Controllers & Meters

Raises the standard in performance for value-driven metal sealed applications.
For many industrial and semiconductor processes, both performance and cost efficiency are crucial. The GF80 Series metal sealed mass flow controllers and meters deliver both: Engineered using the same fast response sensor and patented 4th generation MultiFlo™ technology as our best-selling GF100 series, it’s the right choice for operations that need high performance at a value price point. Moving to a metal sealed MFC brings the full benefit of MultiFloTM multi-gas/multi-range capability since there are no limitations in gases that can be used, enhanced purity of the gas due to elimination of oxygen permeation through elastomers, and a reduction in maintenance since metal seals will last indefinitely.
