The Fluke Calibration P3223-PSI Dual Range Deadweight Tester is a reliable primary pressure standard designed for accurate and repeatable calibration of pressure instruments. Operating with water as the pressure medium, it is well-suited for applications where hydraulic oil is not acceptable. The dual-range configuration enhances versatility, allowing users to perform calibrations over a wide pressure range without compromising precision.
Utilizing the principle of a deadweight tester, the P3223-PSI generates pressure by applying calibrated weights to a high-precision piston-cylinder assembly. This ensures accuracy that is inherently traceable to international standards, making it an ideal choice for ISO/IEC 17025 accredited laboratories.
Key features include:
-
Pressure range: up to 5000 PSI (345 bar)
-
Dual-range operation for extended calibration coverage
-
Water-operated design – clean, oil-free calibration medium
-
Precision piston-cylinder assembly for long-term stability and low uncertainty
-
Built for laboratory and industrial calibration environments
-
Compatible with Fluke mass sets for multiple units of measure
Compatible media: Water or water-based fluids suitable for the tester’s seals.
