Preferably, described workbench is additionally provided with vent valve.
Pass through technique scheme, it is possible to pipeline is carried out Rapid degassing, in order to detect manometric reset capability, it is prevented that owing to after punching press, air gauge pointer can not normally be returned to zero-bit.Also Pressure gauge pressure measurement ability in pressure Rapid Variable Design situation is detected simultaneously.
Preferably, described pipeline is all in below workbench.
Pass through technique scheme, it is possible to avoid causing table surface mixed and disorderly owing to pipeline is in table surface, use and cause interference, the convenience of impact operation with instrument during instrument.
Preferably, described pipeline is flexible pipe.
By technique scheme, pipeline arrangement and convenient when connecting, it is to avoid the design of row of conduits cloth and the trouble that manufactures when using metal tube to connect.
Preferably, described workbench corner is provided with leg, and leg includes the nuts and bolt cooperated, and on the table, bolt is screwed on nut nut-welding, and when laying, bolt head contacts with set-point.
Pass through technique scheme, it is possible to be conveniently adjusted the height of each leg, more stable when making workbench place.
In sum, this utility model in contrast to having the beneficial effect that of prior art and can tested Pressure gauge be calibrated accurately by arranging minute-pressure compression pump and master gauge, avoid owing to supply pressure fluctation affects manometric calibration, vent valve is set on the table simultaneously, and pipeline is arranged on below workbench, Pressure gauge can be detected manometric accuracy when pressure rapid fluctuations, in addition pipeline is arranged on below workbench, table surface can be avoided excessively mixed and disorderly, interfere with other installation tools.
