Description

Technical Field

[0001] The utility model relates to the technical field of chemical preparation sampling, in particular to a sampling device for chemical preparation detection. Background Art

[0002] The use of chemicals is very common in industrial production processes, but some of these chemicals may be harmful to the environment and workers' health. Therefore, in order to monitor the concentration of chemicals in the production process and detect any leakage or contamination in time, it is necessary to use a sampling device to sample and analyze the chemicals. In food processing and production, chemical agents are sometimes needed for disinfection, preservation or other purposes. In order to ensure food safety, it is necessary to monitor the content of residual chemicals in food, and sampling devices can be used to collect samples for testing.

[0003] When testing the liquid to be tested, the existing sampling device for chemical reagent testing can generally only suck one liquid into the test chamber for testing. When it is necessary to test multiple different liquids at one time, the sampling device is limited and cannot test at the same time. It takes a lot of time to test them separately, which is inefficient and has certain limitations when used. Utility Model Content
