Product Overview
The HORIBA STEC SEC-E40 is a high-precision mass flow controller (MFC) engineered for accurate measurement and closed-loop regulation of gas flow in demanding process environments. As a member of the HORIBA STEC SEC-E40 series, this instrument combines a thermal or differential-pressure sensing element with an integrated proportional control valve, delivering stable, repeatable flow control across a wide dynamic range. The SEC-E40 is widely deployed in semiconductor fabrication, thin-film deposition, and precision industrial gas delivery systems where exact flow metering is critical to process yield and product quality. Its compact footprint, fast response time, and multi-gas calibration capability make it a preferred choice for OEM and retrofit installations alike.
