Features: ØEasy sampling at any water depth ØThe water collector goes downstream and takes samples quickly ØIt will not disturb the layering state of the sampling medium and ensure that the water samples are not mixed ØReliable and secure mechanical closure (only a small part is movable) without the need for a rope ØMade of plexiglass, silicide rubber, and electroplated aluminum to ensure no impurities interfere with the sample |

How it works: ØAt the beginning, the plexiglass cover is fixed vertically by a magnet, and the rubber flap is pulled by a steel rope, a few centimeters away from the bottom. ØPut the water collector vertically into the water and sink. The water flow pushes the rubber flap to make it close to the wall of the water collector cylinder, and the water flow passes through the water collector freely without vortex. ØAttain a certain sampling depth and stop the water collector from sinking, the rubber flap falls a few centimeters from the bottom of the plastic ring with magnets. At this time, lift the water collector, the water flow presses down the rubber flap, and the steel rope covers the plexiglassPull it down from the magnet. ØThe magnet in the plastic sealing ring tightly adheres to the rubber flap of the built-in metal material.A sheet spring ensures that the plexiglass cover is closed. |
