The Ashcroft Type 1327CM Gauge Comparator  testers are the most economical, reliable, rugged and  Precision Gauge Comparator testers on the market today. The 1327CM series testers are great for the bench and portable for field work when you can't bring the gauge or instrument into the shop.

The Ashcroft Type 1327CM is a precision gauge comparator which is provided with 6-inch Ashcroft ±0.1% F.S. accuracy Type A4A gauges. The gauges provided include temperature compensation which maintains the ±0.1% F.S. accuracy over an operating range of -25°F to +125°F. Available ranges include 30, 100, 500, 1000, 5000 and 10,000 psi.

Ashcroft^® Types 1327CM are designed to be field- portable pressure generation and test systems. A single carrying case holds the pump used to generate pressure as well as the gauges selected as the test standard.

Ashcroft Type 1327CM are ideally suited for use as in-field pressure standards. Both come with temperature-compensated gauges, further enhancing their 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 for either system. Both systems are traceable to NIST with the 1327CM provided with calibration certificates for each gauge selected.

Units include 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.

Other gauge units of measure are available. kg/cm², bar, and kPa.
