The Fluke Calibration P3125-BAR Deadweight Tester is a precision primary standard designed for accurate, traceable calibration in high-pressure applications. Covering a dual-range from 1 to 1,100 bar (approx. 16,000 PSI / 110 MPa), this tester uses precision-engineered piston-cylinder assemblies and calibrated mass sets to generate stable, repeatable pressure points suitable for laboratory and industrial environments.
Its oil-operated hydraulic system ensures smooth and reliable operation while maintaining long-term stability. The rugged construction and ease of operation make the P3125-BAR ideal for demanding applications in oil and gas, aerospace, power generation, and manufacturing industries.
This dual-range model allows technicians to efficiently calibrate a wide variety of high-pressure instruments while maintaining traceability to international standards and minimizing measurement uncertainty.
