HS701 Pneumatic Pressure Hand Pump is portable structure and designed to generate pressure from vacuum to 6bar. Built-in filter protects the pump from dirty and make maintenance convenient. External air capacitor and shut-off make the micro pressure calibration more stability. Especially the F-adjust valve design make the minimum pressure adjust get 1Pa(0.01mbar) . That is easy to calibrate less than ±25kPa of Micro pressure gauge . 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.
