Abstract: Due to the pressure and electrical instruments in the technical state of the original ship equipment，in a harsh environment，the temperature，humidity，electromagnetic environment，vibration and other parameters cannot meet the requirements and cannot carry out measure calibration.Therefore，a simulation device based on the on-site measurement and calibration environment of ship is designed.The device consists of two parts:environmental control and verification operation.It is focued on constant temperature and humidity technology in high temperature environment，and the structure design of the split verification cabin.The automatic adjustment and controlling of microenvironment is realized.Through the performance test，it is proved that the temperature fluctuation and evenness indexes of the verification cabin meet the design standards，and the environmental condition guarantee problem of site measureing calibration is solved.
