Abstract The 370 digital barometer and the 745 digital barometer are the standard instruments for measuring air pressure,and their performance is different.In this paper,BQY-4000 air piston pressure gauge is used to measure 370 digital barometer and 745 digital barometer.The indication error and stability of two kinds of digital barometers are compared and analyzed,which can be used as reference for digital barometer users.
