Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of water sample collection, in particular to a surface water water sample collector. Background Technique
[0002] Water sample collection is one of the important links in water quality detection. By collecting water samples from polluted water bodies and analyzing and measuring them, basic data on water body pollution can be obtained. The water samples for analysis should be representative and be able to reflect the chemical composition and characteristics of the water body.
[0003] In a water body, the water quality at different depths is different. Therefore, collecting water samples at different depths can better reflect the pollution situation of the water body. For example, for river sampling, if only surface water samples are collected, the pollution situation of the deep water body cannot be reflected. Collecting water samples at different depths can ensure the representativeness of the samples and can more objectively reflect the water quality status. Content of the Utility Model
