AMETEK M&G

AMETEK M&G (Mansfield & Green) is a division of AMETEK Test & Calibration Instruments producing high-accuracy deadweight testers and pressure calibration standards. The brand has a long-standing role in pressure metrology, providing primary pressure references that form the basis for traceable pressure calibration in laboratories and industrial facilities worldwide. AMETEK M&G deadweight testers achieve pressure uncertainties as low as 0.005%, making them suitable for both primary and secondary calibration applications.

The product range covers hydraulic and pneumatic deadweight testers, dual-column pressure standards, and supporting equipment including hydraulic pump kits, water column weights, and pressure accessories. These instruments are used to calibrate pressure gauges, transmitters, transducers, and other pressure measurement devices across a broad span of pressures.
