red-y smart pressure controller – Flow & Pressure in 1 device

Digital Pressure Controllers for Gases with integrated Flow Measurement

The electronic red-y smart pressure controller combine the reliable technology of our digital mass flow controllers with electronic pressure control.
The devices automatically control a predefined process pressure and at the same time measure and/or limit the flow rate. On-the-fly switching between pressure control and flow control offers maximum flexibility.
