Hydro-bios's Multi Limnos automated water sampler is designed to automatically collect 10 water samples at predetermined intervals from a maximum depth of 30 meters of water. The system comes with 10 Duran glass bottles, each of 1L capacity. These bottles are screwed onto a Limnos head and fixed to a base. When the system sinks to the expected depth, all the bottles are closed. They are opened one after another at predetermined intervals. When the bottles are filled with water, they are automatically closed by integrated ball valves.

Multi Limnos has important application value in aquaculture. Automatic water collector and Multi Limnos MST12 multi-channel fallout trap jointly participated in some large-scale aquaculture enterprises in shandong sea cucumber culture zones of water and nutrient cycle research between fallout, has been extremely precious data, for the future of bait on the very scientific mathematical model is established, greatly reduces the production cost of the enterprise.
