[0002] Water sampling can reveal the degree of pollution, chemical composition, and biological indicators of water bodies, thereby assessing whether water quality meets environmental and health standards. It can also help determine the source and type of pollutants, providing a scientific basis for pollution control. One existing water sampling device, such as the one published in CN221898842U, sets the angle between the axis of the sampling bottle and the axis of the telescopic rod to 135 degrees.
