Dwyer Instruments HP-1 | Hand pump
To ensure that pressure instrumentation is calibrated correctly, the Model HP Hand Pump offers two sources of pneumatic pressure and vacuum. Pump has a maximum pressure of 45 psig (3 bar) and a maximum vacuum of -27 in Hg (-910 mbar). The small pump can be operated with just one hand and is meant to be portable. A fine adjustment function and a pressure release valve allow the Model HP to be controlled to better than 0.0015 psi (0.1 mbar). Along with the instruction manual, the pump comes with two 39" (1 m) hoses that terminate in 1/4" female NPT connections.
