QTCM Datasheet, PDF (1/1 Pages) Ralston Instruments. – Nitrogen Calibration Manifolds

Nitrogen Calibration Manifolds
QTCM (3000 psi / 210 bar), QSCM (5000 psi / 350 bar)
The most economical solution for doing static pressure
calibrations with compressed nitrogen gas.
Features:
• Available in both brass (3000 psi / 210 bar) and stainless steel (5000
psi / 350 bar) models
• Fine adjustment piston provides precise pressure control instead of
trying to make adjustments with a pressure regulator and a needle
valve
• Soft-seated valves make filling and venting the system very precise
• Compact design allows the manifold, gauge adapter and hoses to fit
in the included nylon bag
• Because pressure is controlled at the device under test, the nitrogen
cylinder can be mounted on a truck
• Low volume Quick-test hose, gauge adapter and process connection
reduce gas usage and make nitrogen cylinders last longer
• Made in U.S.A.

For manifolds with custom length hoses change first hose (inlet) or second hose (outlet) to desired length. Contact your Ralston Instruments dealer or the
factory for pricing on custom length hoses. For accessories, repair kits and hoses see page 17. For a complete list of accessories and parts see product manual or
detailed specification sheet. For a list of the most commonly used gauge and process connections see page 18. For a complete list refer to Ralston Instruments
Pressure Connection catalog. Contact your Ralston Instruments dealer or the factory for information on reference gauges and pressure calibration kits.
