Dual-valve pressure controllers from Alicat eliminate the need for a bleed valve for pressure control in closed or dead-ended volumes. This allows for responsive and stable control in closed volumes without wasting costly gas through a continuous bleed valve.

Thank you for purchasing an Alicat Gas Flow Controller. Please take the time to read the information contained in this manual. This will help to ensure that you get the best possible service from your instrument. This manual covers the following Alicat Scientific instruments: MC-Series Mass Gas Flow Controllers MCR-Series Mass Gas Flow Controllers Alicat Scientific Single Valve Pressure Controllers and Regulators provide responsive, stable control of absolute, gauge or differential pressures for flowing processes.Differential pressure controllers maintain the pressure differential between two points in a process using separate dead-ended pressure sense ports. Alicat units allow you to measure mass flow, volumetric flow, pressure and temperature simultaneously. If you choose the units with the integrated valves, you can also control flow or pressure with the same device. Choose one of up to 130 gas calibration curves which are already pre-installed or define your own gas mix using COMPOSER™ software. Alicat's PC series pressure controller is more precise than standard manual regulator pressure controller. Versatile A variety of output options including 0-5V, 0-10V and 4-20mA and RS-232 allow users to tailor the PC series pressure controller to their application.
