The US DH-59 is a medium-weight hand-line suspended-sediment sampler. The sampler can be lowered and raised, hand over hand, with a flexible suspension line. It can be used in stream depths up to 15 ft and in steam velocities ranging from 1.5 to 5.0 ft/sec.
The sampler is a streamlined bronze casting that is 15 in long and weighs 22 lbs. The sampler uses a pint glass milk bottle. The bottle 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 rear of the sampler. The sampler uses a 3/16- or 1/4-in internal diameter intake nozzle that projects horizontally upstream from the head of the casting. As a sample is collected, the displaced air in the bottle is ejected downstream through the air exhaust tube integrally cast into the body and protected by a streamlined projection on the side of the head of the sampler. The unsampled zone using the US DH-59 is 4.5 in.
The sampler is calibrated and supplied with nozzles having 1/4” and 3/16” bores. Sample container bottles and the suspension are not furnished with the hand line suspended sediment sampler. The sampler can be used in stream depths up to 15 ft. and in stream velocities ranging from 1.5 to 5.0 ft./sec. The unsampled zone using the US DH-59 is 4.5”. Includes case, hanger bar, 2 gaskets, and 2 ea. of 3/16” and 1/4” red plastic nozzles. HIF Repairable.
Where and how the sampler is deployed in the field is as important as the fundamental design of the sampler. Additional information about how to properly use this sampler can be found in the following references:
