[0002] Water quality monitoring is the process of monitoring and measuring the types of pollutants in water bodies, the concentrations of various pollutants and their changing trends, and evaluating the water quality conditions. The monitoring scope is very wide, including unpolluted and polluted natural water (rivers, lakes, seas and groundwater) and various industrial drainage.

[0003] Existing water quality detection is mainly based on chemical detection, which is to add corresponding chemicals to the sample water to react with the chemical components in the sample water to generate colored substances, and then use color comparison cards to compare the colors to determine the components and content in the sample water. However, this method has cumbersome operating steps, and the waste liquid after the test has a large amount of chemical products, which is not environmentally friendly and cannot be discharged directly. It must be treated before it can be discharged. Therefore, this application proposes a colorimetric device for water quality detection samples that avoids chemical reactions. Utility Model Content
