Ralston QTCM-0000-0-0 QTCM pressure calibration manifold only, no gauge adapter, no hoses, no process connections, no bag



  • 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.
