The Brooks GF135 Thermal Mass Flow Controller combines all of the benefits provided by the most advanced pressure transient insensitive mass flow controller (MFC) and adds real-time flow error detection with advanced diagnostics. The GF135 is a revolutionary pressure transient insensitive (PTI) mass flow controller for semiconductor manufacturing. The advanced diagnostic capabilities let users verify accuracy, check valve leak-by, and monitor sensor drift without stopping production of wafers.

The GF135 has a flow range of 3 sccm to 5 slm and an accuracy of ±1% S.P. The corrosion resistant hastelloy sensor provides unmatched long-term sensor stability ensuring maximum yield. The GF135 delivers up to 3 times faster response and settling time compared to other mass flow controllers.
