Description

Technical Field

[0001] The utility model relates to the technical field of water quality detection, in particular to a portable water quality detection instrument for environmental detection. Background Art

[0002] Water quality detectors are professional instruments used to analyze the content of water components. They mainly refer to instruments for measuring BOD, COD, ammonia nitrogen, total phosphorus, total nitrogen, turbidity, pH, dissolved oxygen and other items in water. In order to protect the water environment, it is necessary to strengthen the monitoring of sewage discharge. Water quality detectors play an important role in environmental protection, water quality testing and water resource protection.

[0003] Referring to the Chinese patent, a portable water quality testing instrument for environmental testing (publication number: CN216013335U, publication date: 2022-03-11) solves the problem that most existing water quality testing instruments are inconvenient to carry and use due to their large size, and most existing water quality testing instruments can only be stored in the laboratory. When the staff needs to use them, they need to collect the water and then bring it back to the laboratory for testing. The operation is too complicated and inconvenient to use, which reduces the work efficiency of the staff. At the same time, there is a lack of cleaning components to clean the inside. Long-term testing will cause residual water quality on the inner wall, resulting in errors in the test results, affecting the accuracy of the test. However, in this patent, the pumped water contains impurities, which can easily cause blockage of the pipeline. In addition, relying on the human eye to observe the water level changes in the test box is sometimes prone to errors, resulting in insufficient or excessive water intake. In this regard, we propose a portable water quality testing instrument for environmental testing to solve the above problems. Utility Model Content
