Aschroft 1327D Hydraulic Pressure Gauge Comparator

     Ashcroft^® Types 1327D is designed to be a field portable pressure generation and test system. A single carrying case holds the pump used to generate pressure as well as the gauges selected as the test standard.

   The 1327D includes an Ashcroft two-stage hydraulic pressure pump. A built-in shuttle valve allows for rapid pressure increase at low pressures. The rate of increase per pump cycle can be reduced at higher pressures in order to minimize resistance. This is accomplished by simply repositioning the two-position shuttle valve. With the shuttle valve in the high-pressure position, increasing pressure even when near 10,000 psi can be accomplished quickly and easily. Final adjustment is accomplished through the use of an integral vernier-adjustment knob.

     The Ashcroft 1327D is available with between one and four Ashcroft gauges covering the operating range of 0 through 10,000 psi. Metric range models are also available. The 1327DG is provided with 4.5" Ashcroft Type 1082 test gauges. These gauges provide an accuracy of +/- 0.25% F.S. The Ashcroft test gauges include temperature compensation and have a maximum thermal error of 0.005% F.S. per degree F.

     Ashcroft Type 1327D is ideally suited for use as in-field pressure standard. The 1327D comes with temperature-compensated gauges, further enhancing it's field worthiness. A single carrying case holds everything needed to take full advantage of the capabilities of the test set. Psi and metric ranges are available.  An NIST Traceable calibration ceritificate can be purchased as an option.
