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

⁄4% Test
Gauges are replaced with from 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 systems available.
