PURPOSE:To improve the inspecting efficiency of the title instrument and, at the same time, to perform one hundred percent inspections. CONSTITUTION:The gas concentration of a drink 12 is measured by utilizing such a characteristic of a sealed container 10 that the rigidity of the container 10 depends upon the pressure in the container 10 and the sugar content of the drink 12 is measured by utilizing the ultrasonic wave propagating speed characteristic of the drink 12. Therefore, both the improvement of the inspecting efficiency and one hundred percent inspections can be achieved, because the gas concentration and sugar content of the drink 12 can be simultaneously measured with accuracy without unstopping the container 10. |
