MKS Instruments 1179B00734CR14V Mass Flow Controller

The MKS Instruments 1179B00734CR14V Mass Flow Controller is a digital Mass-Flo controller designed to measure and precisely regulate gas flow with a full-scale capacity of 30,000 sccm. This Viton-sealed variant (CR14V) is part of the 1179B family, renowned for laminar-flow–based mass measurement and fast warm-up to minimize downtime in production environments. The unit is identified by part number 1179B00734CR14V and ships with Viton elastomer seals (VITON) for chemical compatibility in typical process gases. Listed weights place the controller at about 0.89 kg, reflecting a compact, panel-mountable package that integrates with standard MKS readouts and power supplies. The 1179B series uses a proven measurement technique that delivers stable zero and repeatable flow across its full scale, making it suitable for precise delivery of process gases in semiconductor fabrication, thin-film deposition, and research settings. Applications commonly involve process gas delivery and flow control in gas-handling systems requiring reliable, high-accuracy mass flow control.
