A difference method-based ozone and VOC content measuring system and method, which may simultaneously and accurately monitor in real time the concentration of ozone and VOC and effectively prevent the interference of water vapor, gaseous mercury, organic matter and the like on the measuring system. The measuring system comprises gas intake assemblies, the gas intake assemblies include a standard gas intake assembly for standard gas, a zero gas intake assembly for zero gas, and a sample gas intake assembly for sample gas, wherein the standard gas intake assembly, the zero gas intake assembly and the sample gas intake assembly are connected to a measuring device after passing through a four-way valve; and the measuring device comprises an ozone heating device and an ultraviolet light intensity measuring device that is connected to the ozone heating device. Système et procédé de mesure de teneur en ozone et en COV fondée sur une méthode différentielle, qui peut surveiller simultanément et avec précision en temps
