The Ralston QSCM stainless steel calibration manifold is the easiest and most economical way to perform static pressure calibrations in the field using nitrogen or other compressed inert gas source. The optional hoses and a choice of quick-test NPT adapters provides a integrated kit, and allow direct, finger-tight connections to a wide range of pressure gauges / calibrators and test equipment.

Because pressure can be controlled at the device under test, the nitrogen cylinder can be mounted on a truck. In addition, the low volume Quick-test hoses, gauge adapter and process connections reduce gas usage and make nitrogen cylinders last far longer than using conventional methods.

The entire assembly fits into a zip-up carry bag for easy portability and safe storage.
