Product Description

   Micro pressure vacuum pump is made from high quality and transparent plexiglass material. The operation of piston inside can be seen clearly. The whole structure is more intuitive and compact. This instrument is specially designed to generate micro pressure from vacuum to 50kPa. The F-adjust valve could accomplish 1Pa (0.01mbar) pressure resolution.


HS700 is a very stable Mirco Pressure Calibrator. The design of relieve valve makes the system return to zero pressure quickly. Two standard pressure outputs are easy to connect gauges under test without using the wrenches. The differential port also may connect gauges under test by hose. It widely calibrates micro pressure instruments in field and laboratory.
