The US DH-76 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 streams with depths up to 15 ft and in stream velocities ranging from 1.5 to 6.6 ft/sec. The US DH-76 is similar in design to the US DH-59, but uses a quart glass bottle for additional sample volume, as opposed to the pint bottle used in the US DH-59.

This sampler is a streamlined bronze casting that is 17 in long and weighs 25 lbs. The quart glass bottle 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. As the sampler collects a suspended-sediment sample, the displaced air in the bottle is ejected downstream through an air exhaust tube cast integrally in the body of the sampler and is protected by a streamlined projection alongside the head of the sampler. The sampler uses 3/16- and 1/4-in internal diameter nozzles. The unsampled zone using the US DH-76 is 4 in.

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:
