Description

Technical Field

[0001] The utility model relates to the technical field of water quality monitoring, in particular to a water body sampling device capable of layered sampling. Background Art

[0002] A water sampling device is a piece of equipment or tool used to collect water samples in a water body. It can collect water samples from different depths or locations and usually includes a sampler and related pipe or channel systems. The physical, chemical and biological properties of water bodies may differ in the vertical direction. Through stratified sampling, water samples at different depths or locations can be obtained, which is helpful to study the changes in water quality parameters in the vertical distribution of water bodies. By using a stratified water sampling device, more accurate, comprehensive and reliable water sample data can be obtained, which promotes the development of water environment research, monitoring and protection.
