The common visual colorimetry is a standard series method, namely, different amounts of standard solutions of an object to be detected are used in a group of identical colorimetric tubes, color development is carried out according to an analysis step, and standard color levels with gradually changing colors are prepared. The sample solution is developed under the identical condition, and compared with the standard color level, the standard with the closest color is found visually, and the content of the component to be detected in the sample is calculated and determined according to the amount of the standard solution contained in the standard solution.

In practical use, the influence factors of the light intensity of the light source are more, and the factors such as the length and the shape of the cuvette, the concentration of the liquid to be measured in the cuvette, the alignment distance and the like are more. In the prior art, the installation position of the light source of the water quality detection equipment is installed empirically, and no quantitative method exists. There is a need for a device for calibrating a light source of a water quality testing apparatus that calibrates the light intensity of the light source to an optimal position and improves the detection accuracy.
