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, 1,000, 5,000 and 10,000 psi. When greater accuracy is required but the convenience of a comparator is preferred, the 1327CM affords the best of both worlds in one complete set. Similar to the 1327D, the 1327CM provides the same pump, tools and accessories. However, to achieve greater accuracy the Ashcroft 1/4% test gauges are replaced with 1 to 3 Ashcroft Model A4A precision pressure gauges with a dial size of 6 inches.

Often regarded as the "ultimate master gauge," the Ashcroft A4A precision pressure gauge yields consistent 0.1% of span accuracy in compliance with ASME B40.1, grade 4A. Each gauge is temperature compensated from -25 to +125°F and is provided with a Certificate of Calibration traceable to the NIST. 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. The 1327CM combines the proven accuracy of the Ashcroft precision pressure gauge with the established reliability of the Ashcroft Test Pump to produce one of the most accurate and versatile portable calibration system available.
