Water hydraulic pressure calibration machine dead weight tester

Description of water hydraulic weight tester calibration calibration machine: Water hydraulic weight tester calibration calibration machine is also called a pressure gauge calibrator or a pressure gauge calibration pump. The principle of the pressure gauge calibration machine is that the piston rod movement pressure is increased to achieve the purpose of pressurization. The general pressure gauge (with an accuracy of 1.6 or 2.5) can be tested in a laboratory or in a metering room with a precision pressure gauge (with a precision of up to 0.25). Pressure gauge interface is generally M20 × 1.5 male thread, pressure gauge checker interface is M20 × 1.5 (with M14 × 1.5) ·Stable,labor-saving,steady boost-buck ·Easy to carry,free to maintenance ·Avoid maintenance
