德国HYDRO-BIOS公司--多通道沉积物捕获器Multi Sediment Trap

多通道沉积物捕获器的设计主要用于对相对垂直颗粒流较大的湖泊、大陆架和水栖环境的沉积物的自动采集。在北极、南极、热带、亚热带等环境中，经过无数次的长期野外操作，已经证明了它的可靠性。这款仪器不需要很重的固定线缆，它在较小的船上也可以很容易地安置和收回。多通道沉积物捕获器的控制装置可以执行为期一年多的时间依赖性工作。为了防止捕获到的沉积物从收集筒的上部被冲走，每个收集器在开口处都安装一个可拆卸的塑料网格，捕获器内部完全不含金属。当多通道沉积物捕获器的采集瓶不工作时，它们与周围环境是隔离的。在布放和回收操作期间，收集筒底部是开放的，允许水流自动流过收集筒腔体、�/span>
