The invention provides a wind tunnel experiment synchronous automatic sampling measurement system. The wind tunnel experiment synchronous automatic sampling measurement system comprises an air storagecontrol cabinet system, a gas analysis system and a data acquisition control system, wherein the gas storage control cabinet system comprises a gas storage cylinder, an electromagnetic valve, a vacuum pump and a sampling flowmeter; the gas analysis system comprises a gas analyzer, a gas suction pump, a gas path control plate and a gas path sampling tube; and the sampling measurement system is anN point simultaneous sampling measurement system, is composed of M branching systems, each branching system controls K sampling measurement points, each branch can be independently opened and closed,wherein N is equal to MK, and N, M and K are all positive integers. The wind tunnel experiment synchronous automatic sampling measurement system has the advantages that the measurement precision is guaranteed while the actual r
