Product Overview
The STEC SEC-400MK3 is a high-precision mass flow controller engineered for accurate measurement and regulation of gas and process fluid flow in demanding industrial environments. Operating on a thermal sensing and proportional control principle, this instrument combines a precision flow sensor with an integrated control valve to deliver stable, repeatable flow rates independent of upstream pressure fluctuations. As a process and pneumatic control component, the SEC-400MK3 serves as a critical interface in automated fluid handling systems, providing closed-loop feedback control that maintains setpoint accuracy across varying process conditions. Its compact, modular architecture allows seamless integration into gas delivery panels, semiconductor process tools, and analytical instrumentation where precise flow regulation is essential.
