The piston gauge’s fundamental operating principle and excellent long term stability have

made it an indispensable tool in high accuracy pressure metrology. As accuracy levels increase, quality assurance requirements intensify and automation spreads through the workplace, the piston gauge must evolve to continue to fill its essential role in the measurement system. PG7000, the first truly new, high end piston gauge introduced since the late 1970s, responds to this challenge. PG7000 Piston Gauge line features reference level pressure standards offering a unified solution from vacuum to 500 MPa. The PG7000 Series calibration standards are based on the fundamental principle of mass loaded onto a piston to apply a known force to a known effective area.
