  • Introduction
  • Specifications
Double piston pressure gauge is a pressure standard instrument. It is used to calibrate precise pressure gauge which pressure range is 0～0.25MPa and the vacuum range is 0 ～ -0.1MPa and the accuracy grade is less than 025 grades. It also can be used to calibrate mercury manometer, the non-corrosive industrial pressure gauges or other types of pressure measuring instruments
