The Ashcroft 1327CM is a field-portable pressure generation and test system. The 1327CM offers the ideal combination of a reliable pressure source and a proven secondary standard for those situations when greater accuracy is required but the convenience of a comparator is preferred. Lightweight and fully portable, the 1327CM offers maximum utility in one simple, compact and complete test set.

The 1327CM utilizes a two-stage hydraulic pressure pump and from one to three Ashcroft Type A4A test gauges—used as comparison masters— covering the operating range of 0 through 10,000 psi (or equivalent metric ranges). Since the quality of any calibration is dependent upon the integrity of the comparison standard, high accuracy comparator applications demand the best available master gauge. These 6" gauges are temperature compensated and accurate to 0.1% of span in compliance with the requirements of ASME (formerly ANSI) B40.1, grade 4A.

The pressure pump used with the 1327CM features a built-in two-position shuttle valve which makes it quick and easy to generate either pressures on either end of the spectrum. Final adjustment is accomplished through the use of an integral vernier-adjustment knob. The 1327CM is available in versions to accommodate either petroleum based oils or glycol and phosphate ester based hydraulic fluids. In addition, the 1327CM can be configured to operate with distilled water for the calibration of oxygen service gauges.

The Ashcroft 1327CM 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.
