US DH-95 Depth integrating suspended hand line sampler

HIF/FISP Part # 4101014

The US DH-95 is a hand-line suspended-sediment/water-quality sampler. The sampler can be lowered and raised, hand over hand, with a flexible suspension line. The US DH-95 meets the protocols for water-quality sampling as outlined in the USGS’s National Field Manual for the Collection of Water-Quality Data7. The sampler can be used in stream depths up to 15 ft and in stream velocities ranging from 1.7 to 7.4 ft/sec.

The US DH-95 weighs approximately 29 lbs and is 22 in long with the bottle, cap, and nozzle in place. The bottle cavity is machined from a low-lead bronze casting that is coated with plastic. The tail section is made of high-density polyethylene plastic. The sampler is designed to use a 1-liter Teflon or plastic bottle mated to the US D-95 Cap or US D-77 sampler cap and nozzle. Plastic and TFE nozzles with 3/16-, 1/4-, and 5/16-in internal diameter are available. The recommended sample volume to be collected with the US DH-95 sampler is 800 ml. The unsampled zone using the US DH-95 is 4.8 in.

Includes case, hangar bar, strap, and O-ring retainer. 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:
