Desgranges et Huot – model 5301 – Primary Standard Pressure Calibrator

On Sale Desgranges et Huot – model 5301 – Primary Standard Pressure Calibrator Good condition and ready to use, A high-precision, oil-operated hydraulic dead load (pressure balance) tester designed as a primary pressure standard. Originally manufactured by the renowned French metrology brand Desgranges & Huot (now part of WIKA’s calibration division), it is highly relied upon by national metrology institutes (NMIs), leading calibration laboratories and demanding process industries worldwide.

• Superior Metrological Stability: Because mechanical mass weights do not experience electrical drift over time, the Model 5301 delivers unmatched long-term stability and minimizes the risk of measurement error compared to electronic digital calibrators. [1, 2]
• Interchangeable Piston-Cylinder Units (PCUs): The base unit relies on modular, floating piston assemblies and specialized mass set bells. Operators swap these units out to completely shift the instrument’s targeted pressure range or meet higher uncertainty tolerances. [1]
• Flexible Mass Loading: Designed to accommodate different mass loading bells (typically categorized into short or long variations supporting max mass capacities between 80 kg and 100 kg)
