Sino HS721 Pneumatic Comparator
The HS721 Pneumatic Pressure Comparison Pump has a reverse valve that generates pressure from the vacuum to 140bar. The F-adjust valve has a pressure resolution of 10Pa (0.1mbar). Having three outputs with fast fittings makes it easier to calibrate two under-test pressure instruments at the same time. A built-in gas-oil isolator protects the pump from oil impurities, reducing the need for unnecessary maintenance. The lever lead screw design, in particular, allows the user to operate in a labor-saving mode. It is widely used in the laboratory to calibrate pressure instruments.
