Abstract
An automatic water sampler is disclosed. The automatic water sampler of the present invention comprises: a driving unit operated according to the pressure measured by a pressure sensor; a driving magnet approaching a driven magnet according to the operation of the driving unit; and a first wire unlocked by a control rod according to the movement of the driven magnet. The present invention can provide an automatic water sampler, which improves inaccuracy due to conventional interference of an ocean current, flow velocity, and the like, and manual water sampling by depth by automatically sampling water at the correct depth recognized through a pressure sensor, thereby enabling reliability and accuracy of a sample to be ensured and sampling expenses to be remarkably reduced.
