Sino HS703 Pneumatic Comparator

The HS703 Pneumatic Pressure Comparison Pump has a portable design and can generate pressures ranging from vacuum to 60bar. The built-in filter protects the pump from dirt and makes maintenance simple and easy. The F-adjust valve had a pressure resolution of 10Pa (0.1mbar). The lever lead screw design, in particular, allows the user to operate in a labor-saving mode. The reverse valve’s design makes the transition between vacuum and positive pressure more smooth. Without the use of wrenches, two standard pressure outputs make it simple to connect gauges under test. It calibrates a wide range of pressure instruments in the field and laboratory.
