The Ashcroft 1327D is a field-portable pressure generation and test system. Many calibration applications require only a quick comparison to a master gauge, without the need for a primary deadweight standard. In these applications the Ashcroft 1327D offers the ideal combination of a reliable pressure source and a proven secondary standard. Lightweight and fully portable, the 1327D offers maximum utility in one simple, compact, and complete test set.
The 1327D utilizes a two-stage hydraulic pressure pump and from one to four Ashcroft Type 1082 test gauges - used as comparison masters - covering the operating range of 0 through 10,000 psi (or equivalent metric ranges). These 4.5 inch gauges are temperature compensated and accurate to 0.25% of span in compliance with the requirements of ASME (formerly ANSI) B40.1, grade 3A.
The pressure pump used with the 1327D features a built-in two-position shuttle valve which makes it quick and easy to generate pressures on either end of the spectrum. Final adjustment is accomplished through the use of an integral vernier-adjustment knob. The 1327D is available in versions to accommodate either petroleum based oils or glycol and phosphate ester based hydraulic fluids. In addition, the 1327D can be configured to operate with distilled water for the calibration of oxygen service gauges.
The Ashcroft 1327D pressure gauge comparator includes the tools, adapters and accessories necessary to accommodate most field or lab calibration requirements. All of the components are conveniently stored in a carrying case for maximum protection and portability.
