PROBLEM TO BE SOLVED: To provide a BOD (biochemical oxygen demand) automatic measurement device which automates all of dilution, measuring of D1 values, storage of containers after measuring of D1 values, measuring of D5 values on an exact day of week, and discharge of containers after measuring of D5 values, by merely setting a stock solution.SOLUTION: The BOD automatic measurement device 1 includes a repository 2 which stores sample liquids after D1 values, which are an example of a first value, have been measured until D5 values, which are an example of a second value, are measured; a first measurement device 3 which measures the first values of the sample liquids; and a second measurement device 4 which retrieves the sample liquids from the repository 2 and measures the second values; and it automatically measures the BOD values of the sample liquids based on the first and second values. |
