HS721 Pneumatic Comparator
◆ Pressure Range: (-0.95~60) bar; (-0.95~140)bar
◆ Working Media: Air
◆ Weight: 14.8Kg

Product Description
HS721 Pneumatic Pressure Comparison  Pump is designed with a reverse valve, generated pressure from vacuum to 60bar.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. Especially the lever lead screw design makes user operate in economize labor. It widely calibrates pressure instruments in the laboratory.
