vacuum pump pressure gauge 

Description of pressure calibrator:
Deadweight Tester ( world-wide acceptable )- pressure calibration also known as a  pressure gauge calibration pump,The  pressure gauge calibrator is movement of the piston rod pressure increases,So as to achieve the aim of compression.
    Pressure gauge calibration device is used for testing the pressure source of general pressure gauge, pressure test can reach 60 MPA, inspection vacuum degree can reach -0.08 MPA.
   In laboratory or measuring room generally fit precision pressure gauge (high precision can reach 0.25 magnitude) to detect the ordinary pressure gauge (precision is 1.6 or 2.5).
