Product Overview

The HORIBA STEC LF-F404M-A is a precision mass flow controller engineered for accurate measurement and regulation of gas flow in semiconductor, thin-film, and advanced process environments. As a member of the HORIBA STEC LF series, this instrument combines a thermal or pressure-based flow sensing element with a fast-response proportional control valve to deliver stable, repeatable flow control across a wide dynamic range. The LF-F404M-A functions as a closed-loop process valve assembly, continuously comparing the measured flow signal against a setpoint command and modulating its internal control valve to maintain the desired mass flow rate. It is designed for integration into gas delivery panels, OEM process tools, and industrial gas distribution systems where precise flow metering and leak-tight shutoff are essential.
