FIELD: hydrology; hydrobiology.
SUBSTANCE: device for simultaneous sampling of water samples taken from layers of water laying close to each other, has set of cylinders with pistons disposed onto carrying frame. End parts of all cylinders are hermetically tied with multiplier, which is connected with pump by means of hose pipe. Front edges of all cylinders are provided with beaks having entrance holes for taking water samples. Pistons moves inside cylinders due to hydraulic tie-rod. Space inside hose-pipe, multiplier and end parts of all cylinders is filled with water to avoid corrosion.
EFFECT: improved reliability of efficiency of operation; better protection corrosion.
