HS720 Pneumatic Pressure Comparison Pump is designed with a reverse valve, generated pressure from vacuum to 140bar.The F-adjust valve could accomplish 0.1mbar pressure resolution. Having 2 outputs with fast fittings, which is more effective to calibrate the under test pressure instruments . A built-in gas-oil isolator keeps the pump from oil impurity avoid some unnecessary maintenance.Especially the lever lead screw design makes user operate in economize labor. It widely calibrates pressure instruments in the laboratory.
