An object of the present invention is to increase the accuracy of water quality measurement of ballast waters with different oxidant concentrations. A ballast water measurement apparatus (2 or 62) is provided with: a first measuring unit (6-1 or 64-1) for measuring an oxidant concentration of ballast water after addition of an oxidant or ballast water before addition of a neutralizing agent; a second measuring unit (6-2 or 64-2) for measuring an oxidant concentration of ballast water after neutralization of the oxidant; and a casing (4) that accommodates the first measuring unit and the second measuring unit. Oxidant concentration measurement ranges of the first measuring unit and the second measuring unit are different.
