These instruments are used for checking pressure measuring instruments against master test gauges, indicators or transducers. These hydraulic pressure comparators provide a quick and easy solution for checking pressure measuring instruments to 10,000 psi (700 bar).
A pressure comparator supplies the same precisely controlled pressure to both a reference gauge and device under test for calibration. The P5514 is the preferred manual solution for hydraulic calibration workload below 10,000 psi.
Make it a Pressure Calibrator (P5514-2700G)
The Fluke Calibration P5514 Pressure Comparator when combined with the 2700G Reference Pressure Gauges becomes an easy-to-use alternative to traditional deadweight testers that covers a wide range of workload. For convenience, the P5514 is bundled together with selected 2700G Reference Pressure Gauges for a complete bench top pressure calibration solution. These pressure calibrators provide the accuracy, reliability, and capability you need to calibrate dial gauges, digital test gauges and pressure transmitters.
For example, the P5514-2700G-3 is a P5514 Pressure Comparator, bundled together with 2700G-G70M, 2700G-G20M, 2700G-BG7M. This calibrator has three pressure ranges corresponding to the three 2700G Reference Pressure Gauges in the bundle and covers a total pressure range of –12 psi to 10,000 psi (–80 kPa to 70 MPa).
The accuracy of the calibrator is equal to the accuracy of the 2700G Reference Pressure Gauge being used: ±0.02% full scale of positive pressure or ±0.05% of full scale for vacuum.

|P5521 and P5522 Liquid-to-Liquid Separators||These liquid-to-liquid separators connect directly to the test port of a hydraulic deadweight tester or comparison test pump. A flexible diaphragm separates the fluids, protecting the calibrator from contamination, and allows calibration of the device in its specific working fluid.|
|P5543 Angle Adapter||To calibrate gauges with the pressure connection on the rear (for example, panel mount gauges) in their correct operating position, an angle adaptor should be used. The angle adapter uses the standard gauge adapters and positions the gauges at 90º. The maximum working pressure of this unit is 10,000 psi (700 bar).|
|P5544 Two Gauge Stand||This adapter mounts directly to the test port of the calibrator and allows for the calibration of two instruments at the same time, or the connection of a reference test instrument. Maximum working pressure is 10,000 psi (700 bar).|
|P5551 Pointer Remover / Punch||This tool is designed to quickly remove and consistently refit the pointer of a pressure gauge.|
