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)
Overview
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.
