The utility model discloses a parameter calibrating instrument of a pressure sensor. The parameter calibrating instrument of the pressure sensor is used for being connected to a pressure test system of a well control device to conduct parameter calibration on the pressure sensor. The parameter calibrating instrument comprises a hollow pressure-bearing piece (10) and a quick joint (20) which is fixedly connected to the hollow pressure-bearing piece (10). A hollow inner cavity (1) of the hollow pressure-bearing piece (10) forms a pressure-bearing cavity which is sealed externally and can be communicated with the pressure test system of the well control device through the quick joint (20), and therefore a pressurizing medium coming from the pressure test system of the well control device can enter the hollow inner cavity (1) and be contained in the hollow inner cavity (1). The parameter calibrating instrument of the pressure sensor can be conveniently applied to the pressure test system of the well control devic
