Ralston Calibration Manifolds

  • Two Models- Brass Calibration Manifold 0-3,000 PSI, Stainless Steel Calibration Manifold 0-5,000 PSI
  • 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
