Ralston Calibration Manifold

Product Description

Smooth control of pressure while reducing leaks and saving valuable time in the field.

We’ve simplified the static pressure calibration process with the revolutionary Ralston Calibration Manifold. This unique, hand-held pressure controller provides exceptional control right where you need it most - directly at the device under test.

Available in Brass & Stainless Steel

Solid brass, for pressure calibration from 0 to 3000 psi (model QTCM)

Stainless steel, for pressure calibration from 0 to 5000 psi (model QSCM)

Sku: RAL-QTCM-0000-0-0
Vendor: Ralston
On Back-Order
$621.00 CAD

Precise & Compact Control

Fine adjustment piston with soft-seated valves allow for ultra-precise pressure control

Compact, portable design requires minimum space for operation

Ready for Work

  • Calibration of static or high side of a differential pressure (DP) transmitter
  • Testing of analog gauges on gas well heads up to 5000psi
  • Verification of analog or digital pressure devices in the field up to 5000psi

Acquire Test Points with Ease

The fine adjust piston, along with precision fill and vent valves, allows the technician to quickly reach the test points required to perform static calibrations with less effort and more accuracy.

Ralston Quick-test™ ports for quick & secure connections

Features Ralston Quick-test™ fittings, hoses and adapters for no-tool, no thread tape and leak free connections.
