Product Description
HS703 Pneumatic Pressure Comparison Pump is portable structure and designed to generate pressure from vacuum to 60bar. Built-in filter protects the pump from dirty and make maintenance easy and convenient. The F-adjust valve could accomplish 10Pa (0.1mbar) pressureresolution. Especially the lever lead screw design makes user operate in economize labor. the design of 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 field and laboratory.
