Mass Flow Controller

Mass Flow Controllers for Inert & Aggressive Gases

High Vacuum and Pressure Applications

Can Your Mass Flow Controller Control 30 Different Gases? We Can!

Apex Mass Flow Controllers for vacuum and pressure applications combine flexibility with great accuracy. Our mass flow controllers are multi-gas capable with a flexibility to choose from a list of 98 on-board gases. We offer the option to choose your input and output voltage along with the ability to use RS232 data communications. Using the optional BB9-USB Communications Box our Apex Mass Flow Controllers can control up to 27 Apex devices through one RS232 port, providing your set-up the ultimate flexibility.
