The Ralston Calibration Manifold
Hand-Held Compressed Gas Controller
For calibrating instruments with compressed gas in the field, now there’s a faster, more economical alternative to filling and bleeding valves.
We’ve simplified the static pressure calibration process with the revolutionary Ralston Calibration Manifold. With its fine adjust piston and precision fill and vent valves, there’s no need to fumble around with a rig of multiple valves and fittings back at the truck. This unique, hand-held pressure controller provides exceptional control right where you need it most - directly at the device under test. Designed for simplicity, Calibration Manifolds provide smooth control of pressure while reducing leaks and saving valuable time in the field.
Key Features of the Calibration Manifold
- Fine adjustment piston with soft-seated valves allow for ultra-precise pressure control
- Compact, portable design requires minimum space for operation
- Solid brass, for pressure calibration from 0 to 3000 psi (model QTCM)
- Stainless steel, for pressure calibration from 0 to 5000 psi (model QSCM)
- Intuitive, easy-to-use design
- Includes Ralston Quick-test ™ hoses and adapters for no-tool, no tape connections
- Made in the USA
Benefits of Using a Hand-held Pressure Controller
When performing static pressure calibrations, technicians are often forced to continually over-shoot and under-shoot in order to hit their target pressure. It’s an inexact process that makes it difficult to achieve a specific set point, which can lead to inaccurate results.
Ralston Calibration Manifolds reduce these inaccuracies with smooth control of pressure. 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.
Applications
- Calibration of static or high side of a differential pressure (DP) transducer
- Testing of analog gauges on gas well heads up to 5000 psi
- Verification of analog or digital pressure devices in the field up to 5000 psi
