HS720 Pneumatic Pressure Calibration Pump isdesigned with a reverse valve, generated pressure from vacuum to 140bar.The F-adjust valve could accomplish 10Pa (0.1mbar) pressure resolution. Having 3 outputs with fast fittings, which is more effective to calibrate 2pcs under test pressure instruments together. A built-in gas-oil isolator keeps the pump from oil impurity avoid some unnecessary maintenance. Non-external pipe makes the system avoid the effects of environmental changes. Especially the lever lead screw design makes user operate in economize labor. It widely calibrates pressure instruments in the laboratory.
