Ralston Calibration Manifolds

Ralston Instruments

An excellent solution for doing static pressure calibrations with compressed nitrogen gas. Brass and stainless steel manifolds are available to provide solutions for every type of environment.

Calibration Manifolds

The most economical way of performing static pressure calibrations in the field using nitrogen or other compressed gas.

  • 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.

 

 

Calibration Manifolds with Gauge Connection

Attach a gauge or pressure calibrator directly to the calibration manifold and easily perform static pressure calibrations (pressure gauge not included)

  • 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
  • Low volume Quick-test hose, gauge adapter and process connection reduce gas usage and make nitrogen cylinders last longer
  • Each kit comes with the hoses and gauge or pressure calibrator adapter needed so that you can start calibrating within minutes
  • Made in U.S.A.
