DH59 is an easy-to-use medium-weight suspended sediment sampler.

The sampler consists of an epoxy coated, streamlined bronze casting weighing approx. 10 kg, which partially encloses the sample container. It is equipped with a tail vane assembly to orient the intake nozzle into the approaching flow as the sampler enters the water. With the instrument oriented into the direction of flow (nozzle horizontal and pointed upstream) a continuous stream filament is discharged into the sample bottle during the period of submergence.The axis of the sample container is inclined at an angle to the vertical which permits sampling to within 90 mm of the stream bed.

The sample container is sealed against a gasket in the head cavity of the casting by pressure applied to the base of the bottle by a hand-operated spring-tensioned pull-rod assembly at the tail of the sampler. Suspended sediment samples are discharged into the bottle containers. The air in the bottle is discharged through an air exhaust tube in the body casting. This tube is protected by a streamlined projection alongside the head of the sampler.
