The US DH-2 is a hand-line suspended-sediment/water-quality collapsible-bag sampler capable of collecting a 1-L sample isokinectically to 35 ft. The sampler can be lowered and raised, hand over hand, with a flexible suspension line. The US DH-2 meets the protocols for water quality sampling for a “clean” suspended-sediment sampler as outlined in the USGS’s National Field Manual for the Collection of Water-Quality Data.
The US DH-2 is fabricated from cast bronze and high-density polyethylene and is plastic coated. It is 19” long and weighs 29 lbs. The sampler uses plastic or TFE nozzles and plastic or PFA bags.
The sampler can be used in stream depths up to 35 ft using a 3/16” internal diameter nozzle, 20 ft using a 1/4” internal diameter nozzle, and 13 ft using a 5/16” internal diameter nozzle. The sampler can be used in stream velocities ranging from 2.0 to 6.0 ft/sec.
Includes case, manual, 4 O-rings, 2 bag straps, 1 plastic 1-L bag, 3 Teflon nozzles (3/16”, 1/4”, 5/16”) and a hanger bar.
