Product Description

HS703 Pneumatic Pressure Comparison Pump is a portable structure and designed to generate pressure from
vacuum to 60bar. The built-in filter protects the pump from dirt and make maintenance easy and convenient. The
F-adjust valve could accomplish 10Pa (0.1mbar) pressure resolution. Especially the lever lead screw design
makes the user operate in economize labor. the design of the reverse valve makes the switch of vacuum and positive
pressure more smooth. Two standard pressure outputs are easy to connect gauges under test without using the
wrenches. It widely calibrates pressure instruments in the field and laboratory.
