1179C General Purpose, Elastomer Sealed 10-20,000 sccm Mass Flow Controller
Model: 1179C

Overview
Overview
The 1179C is a general purpose mass flow controller designed to measure and control the flow of gases in a wide variety of applications. The 1179 Mass-Flo® controllers are available with Full Scale ranges from 10 sccm to 20 slm, providing fast, repeatable flow control to as low as 0.2 sccm. It can also be used as a pressure controller when connected to a suitable pressure transducer. The 1179C is a direct form-fit-function replacement for the most common MFCs on the market today. The standard 3-inch footprint enables the 1179C to drop directly into the same space without modifying existing gas lines. Electrical connectors are the same Type "D" connectors, with the same pin-outs, signals, and functions as their industry counterparts, so no cable or connector rewiring is necessary. The 1179C is compatible with MFC power supply and display electronics from MKS or other manufacturers.
