Mansfield & Green (M&G) Deadweight Testers from AMETEK Sensors, Test & Calibration are globally recognized as the gold standard in primary pressure calibration. Based on fundamental physical principles (Pressure = Force / Area), M&G deadweight testers provide intrinsic traceability, unmatched long-term stability, and accuracy of up to 0.015% of reading for precision calibration in laboratories and challenging industrial environments.
Achieve Unmatched Accuracy in Pressure Measurement with the PK II Pneumatic Dead Weight Tester
With an accuracy of up to 0.015% of reading, the PK II dead weight tester is ideal for applications where precision is critical. This makes it suitable for use in industries such as oil and gas, pharmaceuticals, power generation, and research laboratories where maintaining precise pressure control is essential for both safety and performance.
Self-regulating spherical ball floats on a thin air film, eliminating mechanical friction and weight spinning.
Operates using clean air or nitrogen, ideal for oxygen cleaning, medical, and sanitary device calibration.
Quick setup with no rotational drag or hydrodynamic error, delivering consistent readings across all test cycles.
Non-magnetic stainless steel weights calibrated directly to local gravity in psi, bar, kg/cm², or kPa.
Offers Laboratory Accuracy in an Instrument Designed to Withstand an Industrial Environment
The Type T tester is a dead weight tester that offers laboratory accuracy in an instrument designed to withstand an industrial environment. Engineered for heavy-duty pressure testing, it withstands vibration, wide temperature variations, and demanding field conditions without sacrificing precision.
Calibrate transmitters, transducers, and test gauges up to 15,000 psi (1,000 bar / 100 MPa) with complete reliability.
Dual-cylinder assembly allows high resolution and seamless testing across both low and high pressure ranges in one base.
Built-in displacement pump and screw press enable rapid system priming and fine micro-adjustments.
Operates reliably with hydraulic mineral oil, water, or synthetic calibration media with easy drain and refill.
