Achieve total control over your gas

The ControlPak, from Ralston Instruments, is a compressed gas volume controller that can really take a beating. It provides precise control over compressed gas sources for smooth and quick calibration testing. Encased in durable, tactical plastic designed to withstand mud, intense sun, and extreme cold, it is the ideal platform for pressure calibration and pressure testing in the field. With fine control of pressure from 0-3000 psi (0-20 Mpa), you can perform both ultra-precise low-pressure differential or high-pressure static pressure calibrations with a single setup. It includes multiple outlet ports so you can connect a calibrator and your DUT directly without a tee, and its soft-seated valves allow the user to pressurise and depressurise incrementally, so there’s no need for a regulated pressure supply. It also has a built in storage compartment for holding extra hose and adapters. And to top it all off - all outlet connections, hoses and adapters are Ralston Quick-test ™ fittings, which create secure, leak-proof connections without the need for tools or thread tape. The ControlPak provides solid, stable pressure with excellent control over test pressure.
