The utility model provides a high-pressure gauge detection and calibration device, which comprises a human-machine interface (HMI), a programmable logic controller (PLC), an air inlet pipeline and a pressure relief pipeline, an air filter, an oil filter, a stop valve and a total pressure switch are sequentially arranged on the air inlet pipeline from the air inlet end, and then the air inlet pipeline is divided into a low-pressure calibration pipeline, a medium-pressure calibration pipeline and a high-pressure calibration pipeline. A safety valve, a pressure relief pressure switch, a fourth pipeline type flow limiting valve and a pressure relief electric valve are sequentially arranged on the pressure relief pipeline in the airflow flowing direction. Outlets of the three calibration pipelines and an inlet of the safety valve are connected with an instrument to be calibrated through calibration interfaces, and the human-machine interface HMI is connected with the programmable controller PLC to display related
