The Fluke Calibration P3125XT Hydraulic Deadweight Tester is a high-precision primary pressure standard designed to provide reliable calibration for a wide range of pressure instruments. With a measurement span from 1 to 1200 bar (17,400 psi / 120 MPa), this unit ensures accurate, traceable calibrations by generating pressure through precision-machined piston-cylinder assemblies and calibrated mass sets.
Using oil as the pressure medium, the P3125XT delivers stable, repeatable performance suitable for both laboratory and field calibration tasks. Each piston-cylinder assembly is manufactured to exacting tolerances, ensuring long-term reliability and minimal measurement uncertainty. The rugged frame and simple operation make it a durable and dependable choice for calibration professionals.
This model is ideal for applications requiring high-pressure calibration, including power generation, oil and gas, aerospace, and manufacturing industries.
