The utility model discloses a pressure and nitrogen concentration detecting detector and belongs to the technical field of tire detection. The detector comprises a gun body, a handle, an air valve nozzle clamping head, a pressure sensor, an oxygen sensor, a control panel and a PCB board, wherein the handle is movably connected to a side wall of the gun body, one end of the gun body is provided with the air valve nozzle clamping head while the other end of the gun body is provided with the oxygen sensor, an air path between the air valve nozzle clamping head and the oxygen sensor is connected when the handle is pressed down, and the control panel is arranged on the side wall of the gun body; the control panel is provided with a display screen, a function key and a calibration key; the function key is used for switching detection state, the calibration key is used for calibrating pressure and atmosphere concentration, and the PCB board is arranged in the control panel. According to the pressure and nitrogen concentration detecting detector, by operating the function key and the calibration key on the control panel in a simple manner, the detector can flexibly switch between a tire pressure detection mode and a tire inner nitrogen concentration detection mode; the detector is low in manufacture cost and is convenient to popularize and apply.
