The HS700 Micro Pressure Comparison Pump is a precise instrument made of high-quality, transparent plexiglass. The piston operation is visible, and the overall design is compact and easy to use. This instrument is specifically designed to generate micro pressure from vacuum to 0.5 bar. The F-adjust valve provides a pressure resolution of 0.01 mbar. The HS700 is a very stable micro pressure calibrator, and the relief valve allows the system to return to zero pressure quickly. Two standard pressure outputs allow for easy connection of gauges under test without using wrenches. The differential port can also be used to connect gauges under test using a hose. The HS700 is widely used for the calibration of micro pressure instruments in the field and laboratory.
