ControlPak Manual Pressure Controller


Fluid-Free Field Calibration

An integrated volume controller protected by a tough, durable plastic case, the ControlPak provides consistent, stable pressure for calibrating transmitters, gauges, and other pressure instrumentation in the field. Manually adjust regulated nitrogen pressure with utmost precision, right at the source of your DUT.

Full Scale Precision Pressure Control

The ControlPak has impressive turndown, allowing fast, finger-tip control of pressure from 0.03 psi (200 Pa) to 3000 psi (20 MPa). Dial in test pressures to within .0005 psi (.03 mbar) and quickly perform both low-pressure differential or high-pressure static pressure calibrations in a single setup with extreme precision. Mount a Ralston FieldLab, Ralston Field Gauge or any reference device directly for easy reading during calibrations.

Field Ready Construction

The ControlPak is encased in a durable, tactical plastic designed to withstand mud, intense heat, humidity, and extreme cold. Pull it from your truck, connect it to a regulated nitrogen tank, and start calibrating right at the site of your device under test. Combined with the included Ralston Quick-test™ connections, hoses, and reference gauge adapters, the rugged ControlPak includes everything you need for fast, precise control over test pressure - right where you need it.

ControlPak Features

  • Proprietary, pressure-balanced fine adjustment piston allows for extremely precise, control of pressure from 0.03 psi (200 kPa) to 3000 psi (20 MPa), letting you dial in test pressures to within .0005 psi (.03 mbar)
  • Fine adjust piston, fill, balance and vent valves are all included in one light-weight, compact unit
  • Includes handle, Ralston Quick-test ™ fill valve and outlet connections, hoses and adapters
  • Low volume Quick-test hose, gauge adapter and process connection can be attached to ControlPak without thread sealant or a wrench
  • Soft-seated valves make filling and venting the system very precise
  • Made in the U.S.A.
