The Ashcroft® 1327D pressure gauge comparator is a portable pressure generation and test system. With up to four 4½ Ashcroft test gauges, this secondary standard is ideal for quick and reliable calibration.
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. The 1327D utilizes the same pump, tools, box and accessories that are used in the 1305D deadweight tester. However, instead of weights and pistons, the 1327D employs from 1 to 4 Ashcroft model 1082 test gauges as comparison masters.
These gauges have a dial size of 41 ⁄2 inches and are accurate to 0.25%of span in compliance with the requirements of ASME (formerly ANSI) B40.1, grade 3A. The Ashcroft 1082 Test Gauge makes the 1327D the perfect choice for the calibration of 1% F.S. industrial service gauges where a 4:1 accuracy ratio must be maintained. Like the 1305D, 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. Lightweight and fully portable, the 1327D offers maximum utility in one simple, compact and complete test set.
