The Aera FC-985C is a high-performance digital mass flow controller (MFC) designed to deliver precise and repeatable gas flow control for critical processes. Renowned for its stability and reliability, this MFC is widely used in semiconductor manufacturing, thin-film deposition, and other applications requiring accurate gas management. This specific unit, model FC-985CTBF, is calibrated for Nitrogen (N2) gas with a full-scale flow range of 50 SCCM. It operates on a +15V DC power supply and includes a clear flow direction indicator to ensure correct installation and operation in complex gas delivery systems.
