The Ashcroft® 1327D is available with between one and four Ashcroft® gauges covering the operating range of 0 through 10,000 psi. Metric range models are also available, contact FLW for metric range models. The 1327DG is provided with 4.5" Ashcroft® Type 1082 test gauges. These gauges provide an accuracy of ±0.25% F.S. The Ashcroft® test gauges include temperature compensation an have maximum thermal error of 0.005% F.S. per degree F.

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 4 1/2 inches and are accurate to 0.25% of span in compliance with the requirements of the 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. Ashcroft Types 1327CM and 1327D 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.
