Description

Technical Field

[0001] The utility model relates to the technical field of detection, in particular to a heavy metal detection device for a water environment. Background Art

[0002] With the rapid development of industrialization and urbanization, heavy metal pollution in water has become a serious environmental problem, which has had a huge impact on human health and the ecosystem. Therefore, early detection and detection of heavy metal content in water has become an important task in maintaining environmental health and sustainable development. Therefore, a water environment heavy metal detection device has emerged.

[0003] The existing detection device is unable to clean the detection probe used for detection in time after the sample detection is completed. When the next sample is tested, the detection probe will have residues from the previous sample, causing errors in the test results and increasing the workload. At the same time, when reagents need to be added to complete the test, the reagents and samples cannot be mixed quickly, which increases the detection time process. Therefore, we proposed a new water environment heavy metal detection device to solve the above problems. Utility Model Content
