The Ralston Calibration Manifold
Hand-Held Compressed Gas Controller
Ultra-Precise Pressure Control
Reduce leaks and save valuable time in the field with the revolutionary Ralston Calibration Manifold. This unique, hand-held compressed gas controller provides exceptional control right where you need it most - directly at the device under test.
Compact, Intuitive Design
Leave the bulky rig of valves and fittings back at the truck. The portable calibration manifold requires very little space for operation. Just hook up a compressed gas cylinder at one end, a device to be calibrated on the other, and a gauge in the middle. It’s that simple.
Greater Accuracy with Less Effort
Fine-adjustment piston with soft-seated fill and vent valves delivers ultra-precise pressure control, allowing technicians to quickly reach the test points required to perform static calibrations.
Fine-tune Pressure Directly at the Source
- Suitable for calibration of static or high side of a differential pressure (DP) transmitter
- Ideal for testing of analog gauges on well heads up to 5000psi and similar applications where compressed gas is required
- A time-saving tool for verification of analog or digital pressure devices in the field up to 5000psi
Brass & Stainless Steel Options
QTCM Brass Manifold - for pressure calibration from 0 to 3000 psi
QSCM Stainless Steel Manifold - for higher pressure calibration from 0 to 5000 psi, with greater chemical compatibility
