Carbonated beverage carbon dioxide concentration detection equipment

The utility model relates to the technical field of gas detection equipment, in particular to carbonated beverage carbon dioxide concentration detection equipment which comprises a sampling tube, a piston is slidably connected in the sampling tube, a push rod is slidably connected to the sampling tube, and one end, located in the sampling tube, of the push rod is fixedly connected with the piston. By arranging the observation assembly, carbon dioxide in beverages can be filled into the air bag through shaking, after the air bag is fully expanded, the whole device can be inverted, colored liquid is poured to the side, close to the air bag, in the shell, and at the moment, due to the existence of the air bag, the liquid level of the colored liquid can rise; the volume of the colored liquid is observed through the two dial gauges when the air bag exists or not, and the difference between the two values is the volume value of the carbon dioxide in the air bag, so that the content of the carbon dioxide contained i
