The HS703 Pneumatic Pressure Comparison Pump is a portable, easy-to-use instrument that can generate pressure from vacuum to 60 bar. It has a built-in filter that protects the pump from dirt and makes maintenance easy. The F-adjust valve provides a precise pressure resolution of 10 Pa (0.1 mbar). The lever lead screw design makes operation effortless, and the reverse valve design ensures smooth switching between vacuum and positive pressure. Two standard pressure outputs allow for easy connection of gauges under test without the use of wrenches. The HS703 is widely used for the calibration of pressure instruments in the field and laboratory.
