YFP type vacuum pressure hand pump is a quick hand pressure source, by adjusting the pressure vacuum valve can realize the vacuum
pumping and positive pressure, suitable to calibrate kinds of differential pressure, vacuum, vacuum pressure and pressure
instrument, and also can be used as vacuum pressure source of the above pressure instrument. Characteristic of compact size, light
weight, easy to operate, hand held, can can be matched to vacuum pressure instrument.
