The Fluke Calibration P3211-BAR Deadweight Tester is a primary pressure standard designed to deliver accurate, stable, and traceable calibration up to 35 bar (3.5 MPa / 500 PSI). Using a single piston-cylinder unit, it generates precise pressure points through calibrated masses, ensuring repeatable and reliable measurements suitable for laboratory and industrial applications.
Water is used as the operating medium, providing an oil-free calibration environment that reduces contamination risks. The P3211-BAR is compact, robust, and engineered for ease of use, making it ideal for calibration of low- to medium-pressure instruments such as gauges, transmitters, and sensors.
