The Fluke Calibration P5500 Comparison Test Pump is used for checking pressure measuring instruments against master test gauges, indicators or transducers. These cost effective P5500 Comparison Test Pumps are capable of easily generating high pressures under precise control providing a quick and cost-effective means of calibrating pressure instruments.

The P5500 is available in three models: hydraulic, pneumatic and pressure/vacuum. The hydraulic models are capable of generating pressure to 60,000 psi (4200 bar). The hydraulic comparison pumps are compatible with a wide range of fluids and include a high quality screw press for fine pressure adjustments. The pneumatic models are capable of generating pressures to 3500 psi (220 bar) and feature both a screw press and needle valves for fine pressure adjustments. The pressure/vacuum model has a vacuum range of 24 inHg (800 mbar) and a pressure range of 300 psi (20 bar) and includes a high quality needle valve for fine pressure adjustments.

All models of the P5500 Comparison Pumps include test port adapters and test connections that can be made without the need for PTFE tape or wrenches.
