HS721 Pneumatic Comparator
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 avoids some unnecessary maintenance. Especially the lever lead screw design makes users operate in economize labor. It widely calibrates pressure instruments in the laboratory.
