                HYDRO-BIOS: Bottom Sampler acc. to Van Veen
                Category: Dredge Grab
                Art.No.: 437 33x
                Keywords: Van Veen, Bottom Sampler
                Supplier: Qingdao Watertools Technology?Co., Ltd.
                Introduction:

                The Bottom Sampler acc. to Van Veen is a qualitative sampler to achieve low-disturbed sediment samples in soft or medium hard grounds from any desired depth. It consists of two clamshell jaws connected by a hinge. During descent both levers are locked wide apart and the jaws are open. Upon touching the water bed the locking mechanism is released and when the rope is pulled taut to raise the sampler the jaws close. During retrieval the jaws are holding the sample and prevent sample wash-out. Additional flaps on top of the heavy version 437 333 allow to inspect the sample before retrieving.

                用Van Veen采泥器(抓斗式采泥器)可以从任意想要的深度进行采样。在它被沉入水中过程中,两根杆被锁定,并且离得很远,采泥口处于打开」状态。当它与水床接触时,闭合器被释放;当绳缆被〖拉紧并向上拉动时,采泥器口就会关闭∑ 。如下图:
