DH-2 Sediment Sampler

The US DH-2 is a hand-line depth-integrating collapsible-bag suspended-sediment and water-quality Sampler capable of collecting a 1-liter sample. It is 20 inches long, weighs 30 pounds, and has a hollow cavity inside the sampler body. It is fabricated from a bronze casting with a plastic nose-piece and a High Density Polyethylene (HDPE) tail. The bronze casting is plastic coated with commercially available “PlastiDip.” The cavity in the bronze body is plastic lined. The plastic nose-piece holds the nozzle and nozzle holder in place and “snaps” into the sampler body with slight hand pressure. The collapsible bag is attached to the rear of the nozzle holder with a hook-and-loop strap. The US DH-2 meets protocols for water-quality sampling as outlined in the USGS National Field Manual for the Collection of Water-Quality Data.
