Apex Pressure Controllers

Apex Pressure Controllers for vacuum and non-vacuum applications combine pinpoint accuracy with flexibility to specify your application's parameters. Apex Pressure Controllers have the flexibility to configure your own valve orientation to your application specifications, to choose your digital and analog input / output communication preferences, and a vast process connection selection. From high pressure to low pressure to closed volume and open volumes, and even back pressure there is an Apex PC configuration for your application. The ability to measure and control up to 26 Apex devices through one RS232 or USB port, provides your set-up the ultimate amount of flexibility. Choose from the configurations below to find the PC that will best fit your application.

Apex Millitorr Pressure Controllers 0.1 Millitorr to 760 Torr

The Millitorr Apex Pressure Controllers for rough vacuum applications have pressure ranges from 0.1 Millitorr to 760 Torr. Using an external Capacitance Diaphragm Gauge (CDG), the Millitorr Pressure Controller can accurately control pressure for all of your rough vacuum applications. Have a particular place in your process where you want to keep the pressure constant but don't have space for a pressure controller? The External CDG system with the Millitorr PC can do that too with cables as long as 100ft.
